1 ; Rev ; 7/4 EVAUATION KIT AVAIABE 256-Tap, Nonvolatile, SPI-Interface, General Description The nonvolatile, lineartaper, digital potentiometers perform the function of a mechanical potentiometer, but replace the mechanics with a simple 3-wire SPI -compatible digital interface. Each device performs the same function as a discrete potentiometer or variable resistor and has 256 tap points. The devices feature an internal, nonvolatile EEPROM used to store the wiper position for initialization during power-up. The 3-wire SPI-compatible serial interface allows communication at data rates up to 5Mz, minimizing board space and reducing interconnection complexity in many applications. The provide three nominal resistance values: 5kΩ (), 1kΩ (MAX5423), or 2kΩ (MAX5424). The nominal resistor temperature coefficient is 35ppm/ C end-to-end and only 5ppm/ C ratiometric. This makes the devices ideal for applications requiring a low-temperature-coefficient variable resistor, such as low-drift, programmable gainamplifier circuit configurations. The are available in a 3mm x 3mm 8-pin TDFN package, and are specified over the extended -4 C to +85 C temperature range.

Digital Interface and Timing Diagram Detailed Description The contain a resistor array with 255 resistive elements. The has a total end-to-end resistance of 5kΩ; the MAX5423 has an end-to-end resistance of 1kΩ; and the MAX5424 has an end-to-end resistance of 2kΩ. The allow access to the high, low, and wiper terminals for a standard voltage-divider configuration.,, and can be connected in any desired configuration as long as their voltages fall between GND and V DD. A simple, 3-wire, SPI serial interface moves the wiper among the 256 tap points. The nonvolatile memory stores the wiper position and recalls the stored wiper position upon power-up. The nonvolatile memory is guaranteed for 5 years for wiper data retention and up to 2, wiper store cycles. Analog Circuitry The consist of a resistor array with 255 resistive elements; 256 tap points are accessible to the wiper,, along the resistor string between and. Select the wiper tap point by programming the potentiometer through the 3-wire (SPI) interface. Eight data bits, and a control byte program the wiper position. The and terminals of the are similar to the two end terminals of a mechanical potentiometer. The feature power-on reset circuitry that loads the wiper position from the nonvolatile memory at power-up. Digital Interface The use a 3-wire, SPIcompatible, serial data interface (Figure 1 and 2). This write-only interface contains three inputs: chip-select 7
8 (CS), data clock (SCK), and data in (DIN). Drive CS low to enable the serial interface and clock data synchronously into the shift register on each SCK rising edge. The RITE commands (C1, C = or 1) require 16 clock cycles to clock in the command and data (Figure 2a). The COPY commands (C1, C = 1, 11) can use either eight clock cycles to transfer the command bits (Figure 2b) or 16 clock cycles with 8 data bits that are disregarded by the device (Figure 2a). Table 1. Register Map After loading data into the shift register, drive CS high to latch the data into the appropriate potentiometer control register and disable the serial interface. Keep CS low during the entire serial-data stream to avoid corruption of the data. The serial-data timing for the potentiometer is shown in Figures 1 and 2.

9 rite iper Register Data written to this register (C1, C = ) controls the wiper positions. The 8 data bits (D7 to D) indicate the position of the wiper. For example, if DIN =, the wiper moves to the position closest to. If DIN = , the wiper moves closest to. This command writes data to the volatile random access memory (RAM), leaving the NV registers unchanged. hen the device powers up, the data stored in the NV registers transfers to the volatile wiper register, moving the wiper to the stored position. rite NV Register The write NV register command (C1, C = 1) stores the position of the wipers to the NV registers for use at power-up. Alternatively, the copy wiper register to NV register command writes to the NV register. riting to the NV registers, does not affect the position of the wipers. Copy iper Register to NV Register The copy wiper register to NV register command (C1, C = 1) stores the current position of the wiper to the NV register for use at power-up. Copy NV Register to iper Register The copy NV register to wiper register (C1, C = 11) restores the wiper position to the current value stored in the NV register. Standby Mode The feature a low-power standby mode. hen the device is not being programmed, it enters into standby mode and supply current drops to.5µa (typ). Nonvolatile Memory The internal EEPROM consists of a nonvolatile register that retains the last value stored prior to power-down. The nonvolatile register is programmed to midscale at the factory. The nonvolatile memory is guaranteed for 5 years for wiper data retention and up to 2, wiper write cycles. Power-Up Upon power-up, the load the data stored in the nonvolatile wiper register into the volatile wiper register, updating the wiper position with the data stored in the nonvolatile wiper register. This initialization period takes 1µs. Applications Information The are intended for circuits requiring digitally controlled adjustable resistance, such as CD contrast control (where voltage biasing adjusts the display contrast), or programmable filters with adjustable gain and/or cutoff frequency. Positive CD Bias Control Figures 3 and 4 show an application where a voltagedivider or variable resistor is used to make an adjustable, positive CD-bias voltage. The op amp provides buffering and gain to the resistor-divider network made by the potentiometer (Figure 3) or to a fixed resistor and a variable resistor (see Figure 4). 5V 5V 3V 3V MAX5423 MAX5424 V OUT MAX5423 MAX5424 V OUT Figure 3.
