Installation of the monitor to the worksurface one snap at a timeThe following procedure will outline how to correctly wire Workstation Continuous Mini Monitor so as to properly monitor an ESD protected workstation.1. Confirm that the worksurface surface resistance is 5 x 10E8 Ohms or less and has a conductive layer.2. A convenient 120 VAC outlet should be located and tested for proper wiring and grounding. Werecommend the Desco 98130 AC Outlet Analyzer to verify proper wiring and ground.AC AdapterESD MATPark SnapFigure 4. Operating the Jewel® Workstation ContinuousHand Lotion. When leaving the area, a person can take the coil cord along or leave it attached to themonitor in park position.NOTE: Removing the banana plug from the monitor’s operator jack will disable the audio alarm.It is recommended that you use the Park Snap rather than continuously removing the Banana Plug from its jack. Doing so will increase the life span of the operator jack. If your process requires the constant insertion and removal of the banana plug, please contact your Desco Representative for alternate solutions.Specifications:Test range of monitored circuit:500K - 10M ohms†Worksurface Limit*:Set to 500 Megohms ± 20%Operating Voltage:24VAC, 50-60 HzWrist strap open circuit voltage:1.2 Volts peak to peak @ 1-2 MicroAmpsMat test open circuit voltage:5 - 7.5 VoltsResponse time to alarm:<50 mSOperating Temperature:32ºF - 100ºFHumidity Range:0-95% RH, non- c ondensingDimensions:2.77" L x 2.07" W x .71" H† This cannot be verified with standard DC test equipment. The continuous monitor is an impedance sensing device and the limits are determined by the magnitude and angle of the impedance.*Contact factory for special limits.NOTE: Worksurface must have a conductive layer such as Dual Layer Rubber or Dissipative 3-Layer Vinyl or Micastat® Dissipative Laminate with conductive buried layers. Desco continuous monitors are not recommended for use with homogeneous matting.Maintenance and CalibrationThe Jewel® Workstation Continuous Mini Monitor is solid state and designed to be maintenance free. It is calibrated to NIST traceable standards. There are no user adjustments necessary. Because of the wave distortion impedance sensing nature of the test circuit, special equipment is required for calibration. We recommend that calibration be performed annually using the Desco 98220 Continuous Monitor Calibration Unit. The Calibration Unit is a most important product which allows the customer to perform NIST traceable calibration on continuous monitors. The 98220 is designed to be used on the shop floor at the workstation, virtually eliminating downtime, verifying that the continuous monitor is operating within tolerances. The 98220 provides a simple and quick means to assure compliance verificaton Per ANSI/ESD S20.20 Table 3 per ESD TR53.Limited WarrantyDesco expressly warrants that for a period of one (1) year from the dateof purchase Desco Continuous Monitors will be free of defects in material(parts) and workmanship (labor).

V CC has internal 20V clamp with respect to GND.Note 4: This IC includes overtemperature protection that is intended to protect the device during momentary overload conditions. Junction temperature will exceed 125°C when overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability.Note 5: T J is calculated from the ambient temperature T A and power dissipation P DIS according to the formula:T J = T A + (P DIS • 49°C/W)Note 6: The LTC4268-1 operates with a negative supply voltage in the range of –1.5V to –57V. To avoid confusion, voltages in this data sheet are referred to in terms of absolute magnitude. Terms such as “maximum negative voltage” refer to the largest negative voltage and a “rising negative voltage” refers to a voltage that is becoming more negative.Note 7: In IEEE 802.3af systems, the maximum voltage at the PD jack is defined to be –57V.Note 8: The LTC4268-1 is designed to work with two polarity protection diodes in series with the input. Parameter ranges specified in the Electrical Characteristics are with respect to LTC4268-1 pins and are designed to meet IEEE 802.3af specifications when the drop from the two diodes is included. See Applications Information.Note 9: Signature resistance is measured via the two-point D V/D I method as defined by IEEE 802.3af. The LTC4268-1 signature resistance is offset from 25k to account for diode resistance. With two series diodes, the total PD resistance will be between 23.75k and 26.25k and meet IEEE 802.3af specifications. The minimum probe voltages measured at the LTC4268-1 pins are –1.5V and –2.5V. The maximum probe voltages are –9.1V and –10.1V.Note 10: The LTC4268-1 includes hysteresis in the UVLO voltages to preclude any start-up oscillation. Per IEEE 802.3af requirements, theLTC4268-1 will power up from a voltage source with 20Ω series resistance on the first trial.Note 11: Supply current does not include gate charge current to the MOSFETs. See Application Information.Note 12: To disable the 25k signature, tie SHDN to V PORTP (±0.1V) or hold SHDN high with respect to V IN . See Applications Information.Note13: I LIM_EN pin is pulled high internally and for normal operation should be left floating. To disable current limit, tie I LIM_EN to V IN . See Applications Information.Note 14: I IN_CLASS does not include classification current programmed at Pin 3. Total supply current in classification mode will be I IN_CLASS + I CLASS (See Note 15).Note 15: I CLASS is the measured current flowing through R CLASS . ∆I CLASS accuracy is with respect to the ideal current defined as I CLASS = 1.237/R CLASS . T CLASSRDY is the time for I CLASS to settle to within ±3.5% of ideal. The current accuracy specification does not include variations in R CLASS resistance. The total classification current for a PD also includes the IC quiescent current (I IN_CLASS ). See Applications Information.Note 16: This parameter is assured by design and wafer level testing.Note 17: Active high power good is referenced to V NEG and is valid for V PORTP – V NEG ≥ 4V.Note 18: The LTC4268-1 includes a dual current limit. At turn on, before C1 is charged, the LTC4268-1 current level is set to I LIMIT_LOW . After C1 is charged and with I LIM_EN floating, the LTC4268-1 switches to I LIMIT_HIGH . With I LIM_EN pin tied low, the LTC4268-1 switches to I LIMIT_DISA . The LTC4268-1 stays in I LIMIT_HIGH or I LIMIT_DISA until the input voltage drops below the UVLO turn-off threshold or a thermal overload occurs.Note 19: The LTC4268-1 features thermal overload protection. In the event of an over temperature condition, the LTC4268-1 will turn off the power MOSFET, disable the classification load current, and present an invalid power good signal. Once the LTC4268-1 cools below the over temperature limit, the LTC4268-1 current limit switches to I LIMIT_LOW and normal operation resumes.Note 20: I LIMIT_DISA is a safeguard current limit that is activated when the normal input current limit (I LIMIT_HIGH ) is defeated using the I LIM_EN pin. Currents at or near I LIMIT_DISA will cause significant package heating and may require a reduced maximum ambient operating temperature in order to avoid tripping the thermal overload protection.Note 21: Component value range guaranteed by design.elecTrical characTerisTicsThe l denotes the specifications which apply over the full operatingtemperature range, otherwise specifications are at T A = 25°C.

Used to command the LTC4268-1 to present an invalid signature and remain inactive. Connecting SHDN to V PORTP lowers the signature resistance to an invalid value and disables the LTC4268-1 PD interface operations. If unused, tie SHDN to V PORTN. NC (Pin 2): No Internal Connection.R CLASS (Pin 3): Class Select Input. Used to set the current the LTC4268-1 maintains during classification. Connect a resistor between R CLASS and V PORTN. (See Table 2.)I LIM_EN (Pin 4):Input Current Limit Enable. Used for controlling the LTC4268-1 current limit behavior during powered operation. For normal operation, float I LIM_EN to enable I LIMIT_HIGH current. Tie I LIM_EN to V PORTN to disable input current limit. Note that the inrush current limit will always be active. See Applications Information.V PORTN (Pins 5, 6, 7): Power Input. Tie to the PD Input through the diode bridge. Pins 5, 6 and 7 must be electri-cally tied together.NC (Pin 8): No Internal Connection.SG (Pin 9): Secondary Gate Driver Output. This pin pro-vides an output signal for a secondary-side synchronous switch. Large dynamic currents may flow during voltage transitions. See the Applications Information for details. V CC (Pin 10): Converter Voltage Supply. Bypass this pin to GND with 4.7µF or greater. This pin has a 20V clamp to ground. V CC has an undervoltage lockout function that turns on when V CC is approximately 15.3V and off at 9.7V. In a conventional “trickle-charge” bootstrapped configura-tion, the V CC supply current increases significantly during turn-on causing a benign relaxation oscillation action on the V CC pin if the part does not start normally.t ON (Pin 11): Primary Switch Minimum On Time Control.A programming resistor (R Ton) to GND sets the minimum time for each cycle. See Applications Information for details. ENDL Y (Pin 12): Enable Delay Time Control. The enable delay time is set by a programming resistor (R ENDL Y) to GND and disables the feedback amplifier for a fixed time after the turn-off of the primary-side MOSFET. This allows the leakage inductance voltage spike to be ignored for flyback voltage sensing. See Applications Information for details.SYNC (Pin 13): External Sync Input. This pin is used to synchronize the internal oscillator with an external clock. The positive edge of the clock causes the oscillator to dis-charge causing PG to go low (off) and SG high (on). The sync threshold is typically 1.5V. Tie to ground if unused. See Applications Information for details.SFST (Pin 14): Soft-Start. This pin, in conjunction with a capacitor (C SFST) to GND, controls the ramp-up of peak primary current through the sense resistor. It is also used to control converter inrush at start-up. The SFST clamps the V CMP voltage and thus limits peak current until soft-start is complete. The ramp time is approximately 70ms per µF of capacitance. Leave SFST open if not using the soft-start function.OSC (Pin 15): Oscillator. This pin in conjunction with an external capacitor (C OSC) to GND defines the controller oscillator frequency. The frequency is approximately 100kHz • 100/C OSC (pF).FB (Pin 16): Feedback Amplifier Input. Feedback is usually sensed via a third winding and enabled during the flyback period. This pin also sinks additional current to compensate for load current variation as set by the R CMP pin. Keep the Thevenin equivalent resistance of the feedback divider at roughly 3k.V CMP (Pin 17): Frequency Compensation Control. V CMP is used for frequency compensation of the switcher control loop. It is the output of the feedback amplifier and the input to the current comparator. Switcher frequency compensa-tion components are normally placed on this pin to GND. The voltage on this pin is proportional to the peak primary switch current. The feedback amplifier output is enabled during the synchronous switch on time.UVLO (Pin 18): Undervoltage Lockout. A resistive divider from V IN to this pin sets an undervoltage lockout based upon V IN level (not V CC). When the UVLO pin is below its threshold, the gate drives are disabled, but the part draws its normal quiescent current from V CC. The V CC undervolt-age lockout supersedes this function so V CC must be great enough to start the part. The bias current on this pin has hysteresis such that the bias current is sourced when UVLO threshold is exceeded. This introduces a hysteresis at the pin equivalent to the bias current change times the imped-/1042681fc分销商库存信息:LINEAR-TECHNOLOGYLTC4268CDKD-1#PBF LTC4268CDKD-1#TRPBF LTC4268IDKD-1#TRPBF LTC4268IDKD-1#PBF。

不锈钢的炼制
由于不锈钢中比较底的碳含量和含有大量比
铁还容易氧化的元素铬（Cr），而在一般热 力学平衡条件下，Cr 优先于C氧化而溶于渣 中，使得降低高Cr铁水的碳含量十分困难， 所以不锈钢和碳素钢或低合金钢的冶炼有显 著差别。

Sample-and-hold amplifiers
LF198/LF298/LF398
DESCRIPTION
The LF198/LF298/LF398 are monolithic sample-and-hold circuits which utilize high-voltage ion-implant JFET technology to obtain ultra-high DC accuracy with fast acquisition of signal and low droop rate. Operating as a unity gain follower, DC gain accuracy is 0.002% typical and acquisition time is as low as 6µs to 0.01%. A bipolar input stage is used to achieve low offset voltage and wide bandwidth. Input offset adjust is accomplished with a single pin and does not degrade input offset drift. The wide bandwidth allows the LF198 to be included inside the feedback loop of 1MHz op amps without having stability problems. Input impedance of 1010Ω allows high source impedances to be used without degrading accuracy. P-channel junction FETs are combined with bipolar devices in the output amplifier to give droop rates as low as 5mV/min with a 1µF hold capacitor. The JFETs have much lower noise than MOS devices used in previous designs and do not exhibit high temperature instabilities. The overall design guarantees no feedthrough from input to output in the hold mode even for input signals equal to the supply voltages. Logic inputs are fully differential with low input current, allowing direct connection to TTL, PMOS, and CMOS; differential threshold is 1.4V. The LF198/LF298/LF398 will operate from ±5V to ±18V supplies. They are available in 8-pin plastic DIP, 8-pin Cerdip, and 14-pin plastic SO packages.
NOTE: 1. SO and non-standard pinouts.
APPLICATION
• The LF198/LF298/LF398 are ideally suited for a wide variety of
sample-and-hold applications, including data acquisition, analog-to-digital conversion, synchronous demodulation, and automatic test setup
