LT3080EDD-1 快速入门指南说明书
QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 1368AADJUSTABLE LDO LINEAR REGULATORS IN PARALLELLT3080EDD-1 DESCRIPTIONDemonstration circuit 1368A shows adjustable linear regulators in parallel using LT3080-1. Architected as a precision current source and voltage follower, it allows this new regulator to be used in many applica-tions requiring high current, adjustability to zero out-put, and no heat sink. Also the device brings out the collector of the pass transistor to allow low dropout operation when used with multiple supplies.A key feature of the LT3080-1 is the capability to supply a wide output voltage range. By using a refer-ence current through a single resistor, the output voltage can be programmed to any level between zero and 36V. The DC1368A has a reduced input voltage 25V due to input capacitor voltage rating. LT3080-1 incorporates an internal ballast resistor to allow direct paralleling of devices without the need for PC board resistors or sensor resistors. By direct paralleling of four LT3080-1 regulators, the DC1368A is capable of delivering up to 4.4A output current. It can be used as a high current linear regulator, post regulator for switching supply, variable voltage sup-ply or low output voltage power supply.Internal protection circuitry includes current limiting and thermal limiting.LT3080-1 regulator is offered in 8-lead MSOP (with an Exposed Pad for better thermal characteristics) and a 3mm × 3mm DFN.The LT3080-1 datasheet gives a complete description of the part, operation and application information. The datasheet should be read in conjunction with this quick start guide for working on or modifying the demo circuit 1368A.Design files for this circuit board are available. Call the LTC factory., LTC and LT are registered trademarks of Linear Technology Corporation.Table 1.Performance Summary ( T A = 25o C )PARAMETER CONDITION VALUE Minimum Vin Voltage Vout=1.2V 1.7V Maximum Vin Voltage 25V Minimum Vcontrol Voltage Vout=1.2V 2.8V Maximum Vcontrol Voltage 25V Output Voltage Iout=4.4A 1.17V ±3% Minimum Output Current 4mA Maximum Output Current Vin-Vout<2.5V 4.4AQUICK START PROCEDUREThe DC1368A is easy to set up to evaluate the per-formance of the LT3080-1. Refer to Figure 1. for proper measurement equipment setup and following the procedures below: 1.Apply 1.7V across Vin (to Gnd), and 2.8V across Vcontrol. Draw 4.4A of load current. The measured Vout should be 1.17V ± 3% (1.13V to 1.21V).2.Vary Vin from 1.7V to 25V, Vcontrol from 2.8V to 25V and the load current from 4mA to 4.4A. Vout should measure 1.19V ± 5% (1.13V to 1.25V).Note: Make sure the power dissipation is limited be-low the thermal limit.Figure 1. Proper Measurement Equipment SetupFigure 2. Measuring Input or Output RippleINPUT VOLTAGE RANGEThe guaranteed Vin dropout voltage is 0.5V at 4.4A, the guaranteed Vcontrol dropout voltage is 1.6V at 4.4A. The maximum Vin and maximum Vcontrol is reduced to 25V due to the input capacitor voltage rat-ing.DUAL SUPPLY OR SINGLE SUPPLYUse two separate supplies for Vin and Vcontrol, a low dropout voltage can be achieved on the Vin pin and the power dissipation is minimized. Alternatively, Tying the Vcontrol to Vin through a zero ohm jump resistor R1 on board, a single supply is sufficient to drive the demo circuit 1368A. AVOID USING A LONG WIRE TO TIE VCONTROL AND VIN.OUTPUT CURRENTThe output current will decrease at high input-to-output differential. The actual current output is further limited by the thermal shutdown function, which is related to the board thermal dissipation.THERMAL IMAGEAn example thermal image shows the temperature distribution on board. The test is done in still air at room tempera-ture with average 2.0W power dissipation in each LT3080-1.BYPASS CAPACITORSince the SET pin is a high impedance node, unwanted signals may couple into the SET pin and cause erratic behavior. This will be most noticeable when operating with minimum output capacitors at full load current. The easiest way to remedy this is to bypass the SET pin with a small amount of capacitance from SET to ground, 10pF to 20pF is sufficient. A 0.01uF bypasscapacitor is used on the demo board to provide a low-noise output. Please refer to datasheet for details.。

NSA-3080日常维护手册24页word
NSA-3080 维护培训手册一、日常维护及检查内容1. 气体分析仪（NSA-3080）的日常维护定概述：仪器的校准建议每两周进行一次（根据国家环境保护总局《HJ/75-2007》之规定每 15 天应进行一次标定），通常情况下（仪表间内温湿度稳定）仪表漂移不会超过 2%F。
S/ 月，如使用者对准确度有怀疑，或有其他需要可按需随时标定。
1 标定的准备工作：首先准备对 URA-208 气体分析仪的操作面板进行操作测量界面在测量界面下按《F2》键进入菜单界面菜单界面将光标移动到“校正条件”按《ENT》键进入校正条件界面校正界面-1根据铝瓶上标准气体的名称和浓度输入到图示界面中的相应气体跨度上（如本图所示，SO2 的跨度气体浓度是286mg/m3。
如需要调整，按《+》《-》键进行调整，调整结束后按《ENT》键进行确认。
（通常情况下，界面中已按照量程设定了所需的浓度值，因此数值调节范围不大。
如需调整的数字与当前值偏差较多，请先按住《F1》健不动按《ENT》键，此时会在数字底部出现闪烁光标，按《←》《→》调节闪烁光标到所需要变更的数字下，再按《+》《-》键进行调整，调整结束后按《ENT》键进行确认即可）标准气体浓度的换算：当标准气体铝瓶上的单位是mg/m3 时，可按标气瓶上的数据直接输入。
当标准气体铝瓶上的单位是10-6 或ppm 时，请按下列公式将浓度进行换算，将换算后的气体浓度输入到分析仪中。
SO2： 1ppm(1*10-6)=64/22.4=2.86 mg/m3NO：1ppm(1*10-6)=30/22.4=1.34 mg/m3CO：1ppm(1*10-6)=28/22.4=1.25 mg/m3另当NO 作为NOx 计算排放量时，应以NO2 计算。
故NOx 浓度为NO 浓度的校正界面-2O2 的跨度根据所在地空气中的O2 含量设定，通常情况下海拔500m 以下时为（20.8%-21%），海拔越低越接近21%；校正界面-3校正界面-4校正界面-5校正界面-6校正条件4、5、6 分别为导入标准气体的时间和稳定、标定时间等参数，可参照《URA-208》说明书或其上显示的中文含义理解，不再详述（如不了解，保持默认设置即可）校正界面-7校正允许范围是设定仪表两次标定的最大偏差，主要是为了防止出现标定不当，或标气用尽等情况令仪表测量失真。
