数字电位器max5402中文资料

Max5402的H脚与L脚之间包含255个串联的固定电阻。

可调端（W引脚)可以通过编程连到任意一个抽头上。

Max5402具有SPI兼容的三线串行数据接口，这个只写（write-only)的接口包含三个输入：片选（CS非），数据in（DIN），和数据时钟（SCLK）。

当CS非是低时，在每一个SCLK脉冲的上升沿（图1），Din脚出来的数据同步的装载到8位串行移位寄存器。

MSB先移动，如图3所示。

注意，如果CS非在全部数据流期间没有一直保持低电平，数据将被破坏，需要重新下载。

当8位数据全部装载到移位寄存器后，一旦CS非为高电平，数据立即锁存到解码器。

解码器使电位器抽头移动到8bit输入数据对应的位置。

对于max5402，每一个电阻单元是10KΩ/256,即39..2Ω。

Max5402具有POR电路特性。

当上电时，通过将二进制数128移到锁存器，电位器抽头处于
中间位置。

将W连接到H或L，可以当作可变电阻。

MAX5842MEUB+中文资料

General DescriptionThe MAX5842 is a quad, 12-bit voltage-output, digital-to-analog converter (DAC) with an I 2C ™-compatible, 2-wire interface that operates at clock rates up to 400kHz. The device operates from a single 2.7V to 5.5V supply and draws only 230µA at V DD = 3.6V. A power-down mode decreases current consumption to less than 1µA. The MAX5842 features three software-selec-table power-down output impedances: 100k Ω, 1k Ω,and high impedance. Other features include internal precision Rail-to-Rail ®output buffers and a power-on reset (POR) circuit that powers up the DAC in the 100k Ωpower-down mode.The MAX5842 features a double-buffered I 2C-compati-ble serial interface that allows multiple devices to share a single bus. All logic inputs are CMOS-logic compati-ble and buffered with Schmitt triggers, allowing direct interfacing to optocoupled and transformer-isolated interfaces. The MAX5842 minimizes digital noise feedthrough by disconnecting the clock (SCL) signal from the rest of the device when an address mismatch is detected.The MAX5842 is specified over the extended tempera-ture range of -40°C to +85°C and is available in a miniature 10-pin µMAX package.

The device consists of a serial interface, power-down cir-cuitry, four input and DAC registers, four 12-bit resistor string DACs, four unity-gain output buffers, and output resistor networks. The serial interface decodes the address and control bits, routing the data to the proper input or DAC register. Data can be directly written to the DAC register, immediately updating the device out-put, or can be written to the input register without changing the DAC output. Both registers retain data as long as the device is powered.DAC OperationThe MAX5842 uses a segmented resistor string DAC architecture, which saves power in the overall system and guarantees output monotonicity. The MAX5842’s input coding is straight binary, with the output voltage given by the following equation:where N = 12 (bits), and D = the decimal value of the input code (0 to 4095).Output BufferThe MAX5842 analog outputs are buffered by preci-sion, unity-gain followers that slew 0.5V/µs. Each buffer output swings rail-to-rail, and is capable of driving 5k Ωin parallel with 200pF. The output settles to ±0.5LSB within 4µs.Power-On ResetThe MAX5842 features an internal POR circuit that ini-tializes the device upon power-up. The DAC registersare set to zero scale and the device is powered down,with the output buffers disabled and the outputs pulled to GND through the 100k Ωtermination resistor.Following power-up, a wake-up command must be initi-ated before any conversions are performed.Power-Down ModesThe MAX5842 has three software-controlled, low-power, power-down modes. All three modes disable the output buffers and disconnect the DAC resistor strings from REF, reducing supply current draw to 1µA and the reference current draw to less than 1µA. I n power-down mode 0, the device output is high imped-ance. I n power-down mode 1, the device output is internally pulled to GND by a 1k Ωtermination resistor.I n power-down mode 2, the device output is internally pulled to GND by a 100k Ωtermination resistor. Table 1shows the power-down mode command words.Upon wake-up, the DAC output is restored to its previ-ous value. Data is retained in the input and DAC regis-ters during power-down mode.Digital InterfaceThe MAX5842 features an I 2C/SMBus-compatible 2-wire interface consisting of a serial data line (SDA)and a serial clock line (SCL). The MAX5842 is SMBus compatible within the range of V DD = 2.7V to 3.6V. SDA and SCL facilitate bidirectional communication between the MAX5842 and the master at rates up to 400kHz.Figure 1 shows the 2-wire interface timing diagram. The MAX5842 is a transmit/receive slave-only device, rely-ing upon a master to generate a clock signal. The mas-ter (typically a microcontroller) initiates data transfer on the bus and generates SCL to permit that transfer.A master device communicates to the MAX5842 by transmitting the proper address followed by commandand/or data words. Each transmit sequence is framedMAX5842Quad, 12-Bit, Low-Power, 2-Wire, SerialVoltage-Output DAC_______________________________________________________________________________________9by a START (S) or REPEATED START (S r ) condition and a STOP (P) condition. Each word transmitted over the bus is 8 bits long and is always followed by an acknowledge clock pulse.The MAX5842 SDA and SCL drivers are open-drain outputs, requiring a pullup resistor to generate a logic high voltage (see Typical Operating Circuit). Series resistors R S are optional. These series resistors protect the input stages of the MAX5842 from high-voltage spikes on the bus lines, and minimize crosstalk and undershoot of the bus signals.Bit TransferOne data bit is transferred during each SCL clock cycle. The data on SDA must remain stable during the high period of the SCL clock pulse. Changes in SDA while SCL is high are control signals (see STAR T andSTOP Conditions). Both SDA and SCL idle high when the I 2C bus is not busy.START and STOP ConditionsWhen the serial interface is inactive, SDA and SCL idle high. A master device initiates communication by issu-ing a START condition. A START condition is a high-to-low transition on SDA with SCL high. A STOP condition is a low-to-high transition on SDA, while SCL is high (Figure 2). A START condition from the master signals the beginning of a transmission to the MAX5842. The master terminates transmission by issuing a not acknowledge followed by a STOP condition (see Acknowledge Bit (ACK )). The STOP condition frees the bus. I f a repeated START condition (Sr) is generated instead of a STOP condition, the bus remains active.When a STOP condition or incorrect address is detect-ed, the MAX5842 internally disconnects SCL from the serial interface until the next START condition, minimiz-ing digital noise and feedthrough.Early STOP ConditionsThe MAX5842 recognizes a STOP condition at any point during transmission except if a STOP condition occurs in the same high pulse as a START condition (Figure 3). This condition is not a legal I 2C format; at least one clock pulse must separate any START and STOP conditions.Repeated START ConditionsA REPEATED START (S r ) condition may indicate a change of data direction on the bus. Such a change occurs when a command word is required to initiate a read operation. S r may also be used when the bus master is writing to several I 2C devices and does not want to relinquish control of the bus. The MAX5842 ser-ial interface supports continuous write operations with or without an S r condition separating them. ContinuousM A X 5842Quad, 12-Bit, Low-Power, 2-Wire, Serial Voltage-Output DAC 10read operations require S r conditions because of the change in direction of data flow.Acknowledge Bit (ACK)The acknowledge bit (ACK) is the ninth bit attached to any 8-bit data word. ACK is always generated by the receiving device. The MAX5842 generates an ACK when receiving an address or data by pulling SDA low during the ninth clock period. When transmitting data,the MAX5842 waits for the receiving device to generate an ACK. Monitoring ACK allows for detection of unsuc-cessful data transfers. An unsuccessful data transfer occurs if a receiving device is busy or if a system fault has occurred. I n the event of an unsuccessful data transfer, the bus master should reattempt communica-tion at a later time.Slave AddressA bus master initiates communication with a slave device by issuing a START condition followed by the 7-bit slave address (Figure 4). When idle, the MAX5842waits for a START condition followed by its slaveaddress. The serial interface compares each address value bit by bit, allowing the interface to power down immediately if an incorrect address is detected. The LSB of the address word is the Read/Write (R/W ) bit.R/W indicates whether the master is writing to or read-ing from the MAX5842 (R/W = 0 selects the write condi-tion, R/W = 1 selects the read condition). After receiving the proper address, the MAX5842 issues anACK by pulling SDA low for one clock cycle.The MAX5842 has four different factory/user-pro-grammed addresses (Table 2). Address bits A6through A1 are preset, while A0 is controlled by ADD.Connecting ADD to GND sets A0 = 0. Connecting ADD to V DD sets A0 = 1. This feature allows up to four MAX5842s to share the same bus.Write Data FormatIn write mode (R/W = 0), data that follows the address byte controls the MAX5842 (Figure 5). Bits C3-C0 con-figure the MAX5842 (Table 3). Bits D11-D0 are DAC data. I nput and DAC registers update on the falling edge of SCL during the acknowledge bit. Should the write cycle be prematurely aborted, data is not updated and the write cycle must be repeated. Figure 6 shows two example write data sequences.Extended Command ModeThe MAX5842 features an extended command mode that is accessed by setting C3-C0 = 1 and D11-D8 = 0.The next data byte writes to the shutdown registers (Figure 7). Setting bits A, B, C, or D to 1 sets that DACFigure 2. START and STOP ConditionsFigure 3.

Any combination of the four DACs can be controlled with a single write sequence.Read Data FormatIn read mode (R/W = 1), the MAX5842 writes the con-tents of the DAC register to the bus. The direction of data flow reverses following the address acknowledge by the MAX5842. The device transmits the first byte of data, waits for the master to acknowledge, then trans-mits the second byte. Figure 8 shows an example read data sequence.I 2C CompatibilityThe MAX5842 is compatible with existing I 2C systems.SCL and SDA are high-impedance inputs; SDA has an open drain that pulls the data line low during the ninth clock pulse. The Typical Operating Circuit shows a typ-ical I 2C application. The communication protocol sup-ports the standard I 2C 8-bit communications. The general call address is ignored. The MAX5842 address is compatible with the 7-bit I 2C addressing protocol only. No 10-bit address formats are supported.Digital Feedthrough SuppressionWhen the MAX5842 detects an address mismatch, the serial interface disconnects the SCL signal from the core circuitry. This minimizes digital feedthrough caused by the SCL signal on a static output. The serial interface reconnects the SCL signal once a valid START condition is detected.Applications InformationDigital Inputs and Interface LogicThe MAX5842 2-wire digital interface is I 2C/SMBus compatible. The two digital inputs (SCL and SDA) load the digital input serially into the DAC. Schmitt-trigger buffered inputs allow slow-transition interfaces such as optocouplers to interface directly to the device. The digital inputs are compatible with CMOS logic levels.Power-Supply Bypassing andGround ManagementCareful PC board layout is important for optimal system performance. Keep analog and digital signals separate to reduce noise injection and digital feedthrough. Use a ground plane to ensure that the ground return from GND to the power-supply ground is short and low impedance. Bypass V DD with a 0.1µF capacitor to ground as close to the device as possible.Chip InformationTRANSISTOR COUNT: 17,213PROCESS: BiCMOSFigure 6.
