EVALUATION KIT AVAILABLE MAX5386/MAX5388 Dual, 256-Tap, Volatile, Low-Voltage Linear Taper Digital Potentiometers General Description Features The MAX5386/MAX5388 dual, 256-tap, volatile, low- voltage linear taper digital potentiometers offer three endto-end resistance values of 10k, 50k, and 100k. Operating from a single +2.6V to +5.5V power supply these devices provide a low 35ppm/C end-to-end temperature coefficient. The devices feature an SPI interface. The small package size, low supply voltage, low supply current, and automotive temperature range of the MAX5386/MAX5388 make the devices uniquely suitable for the portable consumer market and battery-backup industrial applications. The MAX5386 includes two digital potentiometers in a voltage-divider configuration. The MAX5388 includes one digital potentiometer in a voltage-divider configuration and one digital potentiometer in a variable-resistor configuration. The MAX5386/MAX5388 are specified over an extended -40C to +125C temperature range and are available in 16-pin, 3mm x 3mm TQFN or 10-pin, 3mm x 5mm MAX(R) packages, respectively.

Voltage-Divider/Variable-Resistor Configurations www.maximintegrated.com Maxim Integrated 7 MAX5386/MAX5388 Dual, 256-Tap, Volatile, Low-Voltage Linear Taper Digital Potentiometers Detailed Description The first bit A0 (address bit) addresses one of the two potentiometers; writing a zero in A0 addresses control register A and writing a one in A0 addresses control register B. See Table 1. The power-on reset (POR) circuitry sets the wiper to midscale (D[7:0] 1000 0000). The MAX5386/MAX5388 dual, 256-tap, volatile lowvoltage linear taper digital potentiometers offer three endtoend resistance values of 10k, 50k, and 100k. Each potentiometer consists of 255 fixed resistors in series between terminals H and L. The potentiometer wiper, W, is programmable to access anyone of the 256 tap points on the resistor string. The 8 data bits (D7-D0) indicate the position of the wiper. For D[7:0] = 0000 0000, the wiper moves to the position closest to L. For D[7:0] = 1111 1111, the wiper moves closest to H. D[7:0] is 1000 0000 following poweron for both registers A and B. The potentiometers in each device are programmable independently of each other. The MAX5386/MAX5388 have an SPI interface. Register A: The data byte writes to register A, and the wiper of potentiometer A moves to the appropriate position at the rising edge of CS. D[7:0] indicates the position of the wiper. D[7:0] = 0000 0000 moves the wiper to the position closest to L. D[7:0] = 1111 1111 moves the wiper to the position closest to H. D[7:0] is 1000 0000 following power-on. SPI Digital Interface The MAX5386/MAX5388 include an SPI interface, which provides a 3-wire write-only serial data interface to control the wiper tap position through inputs chip select (CS), data in (DIN), and data clock (SCLK). Drive CS low to load data from DIN synchronously into the serial shift register on the rising edge of each SCLK pulse. The MAX5386/ MAX5388 load the last 9 bits of clocked data once CS transitions high. See Figures 2 and 3. After all the data bits are shifted in, data are latched into the appropriate potentiometer control register when CS goes from low to high. Data written to a memory register immediately updates the wiper position. Keep CS low during the entire data stream to prevent the data from being terminated. Register B: The data byte writes to register B, and the wiper of potentiometer B moves to the appropriate position at the rising edge of CS. D[7:0] indicates the position of the wiper. D[7:0] = 0000 0000 moves the wiper to the position closest to L. D[7:0] = 1111 1111 moves the wiper to the position closest to H. D[7:0] is 1000 0000 following power-on. Table 1.
