128-Tap, Nonvolatile, Linear-Taper Digital Potentiometer in 2mm x 2mm DFN Package
General Description
The MAX5128 nonvolatile, single, linear-taper, digital potentiometer performs the function of a mechanical potentiometer, but replaces the mechanics with a simple 2-wire digital interface. The MAX5128 performs the same function as a discrete potentiometer or variable resistor and features 128 taps and 22k end-to-end resistance. The MAX5128 also features an ultra-small, 2mm x 2mm DFN package and low 0.5A (typ) standby supply current, making this device ideal for portable applications. The MAX5128 operates from a +2.7V to +5.25V power supply. An integrated nonvolatile memory recalls the programmed wiper position of the digital potentiometer. A simple 2-wire up/down interface programs the wiper position. The digital potentiometer provides a low 5ppm/C ratiometric temperature coefficient and is specified over the extended -40C to +85C temperature range.

Note 1: All devices are production tested at TA = +25C and are guaranteed by design for TA = -40C to +85C. Note 2: The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VCC and L = GND. The wiper terminal is unloaded and measured with a high input-impedance voltmeter. Note 3: The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = GND. For the +5V condition, the wiper terminal is driven with a source current of 200A and for the +2.7V condition, the wiper terminal is driven with a source current of 100A. Note 4: The wiper resistance is measured using the source currents given in Note 3. Note 5: The device draws higher supply current when the digital inputs are driven with voltages between (VCC - 0.5V) and (GND + 0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics. Note 6: Wiper at midscale with a 10pF load, L = GND, an AC source is applied to H, and the output is measured as 3dB lower than the DC W/H value in dB. Note 7: Wiper-settling time is the worst-case 0 to 50% rise time measured between consecutive wiper positions. H = VCC, L = GND, and the wiper terminal is unloaded and measured with a 10pF oscilloscope probe. See the Tap-to-Tap Switching Transient in the Typical Operating Characteristics section. Note 8: Power-up settling time is measured from the time VCC = 2.7V to the wiper settling to 1 LSB of the final value.

Detailed Description
The MAX5128 nonvolatile, single, linear-taper, digital potentiometer performs the function of a mechanical potentiometer or variable resistor, but replaces the mechanics with a simple 2-wire digital interface. This device features 128 taps and 22k end-to-end resistance with a 5ppm/C ratiometric temperature coefficient. The MAX5128 operates from a +2.7V to +5.25V power supply and consumes only 0.5A (typ) of standby supply current. The MAX5128 includes an integrated nonvolatile memory that recalls the stored wiper position of the digital potentiometer. A simple 2-wire up/down interface programs the wiper positions.
Analog Circuitry
The MAX5128 consists of a resistor array with 127 resistive elements; 128 tap points along the resistor string between H and L are accessible to the wiper, W. Select the wiper tap point by programming the potentiometer through the 2-wire (UP, DN) interface. The MAX5128 features power-on reset circuitry that loads the wiper position from the nonvolatile memory at power-up. The nonvolatile memory is programmed to midscale at the factory.

Digital Interface
The MAX5128 features a 2-wire interface consisting of two logic inputs (UP and DN). Logic inputs UP and DN control the wiper position and program the position to the nonvolatile memory. Transition UP from high to low with DN low to increment the wiper position. Transition DN from high to low with UP low to decrement the wiper position (see Figures 1, 2, and 3). When the wiper decrements, it decreases the resistance between W and L (and it increases the resistance between H and W). To program the nonvolatile memory, force UP high, then force DN high, and then transition either input (UP/DN) from high to low (see Figure 3). The wiper performs a make-before-break transition, ensuring that an open circuit during a transition from one resistor tap to another does not occur. The wiper does not wrap around when it reaches either end of the resistor array (max/min). Additional transition com-
mands in the direction of the end point do not change the tap position. The logic inputs also feature pulse glitch immunity (20ns) to protect the wiper from transitioning due to glitches (see Figure 4). Write NV Register The internal EEPROM consists of a 7-bit nonvolatile memory that retains the value written to it even after power-down. To program the nonvolatile memory, force UP high, then force DN high, and then transition either input (UP/DN) from high to low. A nonvolatile write requires a busy time of 14ms (max). During the busy time, any nonvolatile write requests are ignored as well as requests to increment or decrement the wiper position. Upon power-up, the wiper returns to the position stored in the nonvolatile register. The MAX5128 features a factory-default wiper position of midscale.

Standby Mode
The MAX5128 operates in standby mode while the serial interface is inactive. Programming the MAX5128 increases the average operating current to 400A (max). When in standby mode, the static supply current reduces to less than 0.5A (typ).
DC-DC Converter Applications
Figures 6 and 7 show two applications using the MAX5128 to adjust the output voltage of a DC-DC converter. Figure 6 shows the MAX5128 in the grounded potentiometer configuration. Figure 7 shows the MAX5128 in a floating potentiometer configuration. The grounded potentiometer configuration forces the output voltage range of the DC-DC converter to fall within the supply voltage range of the MAX5128. Use the floating potentiometer configuration to allow the DC-DC converter's output to exceed the supply voltage range of the MAX5128. The floating potentiometer configuration increases the output voltage range and increases the precision of the output voltage adjustment range.
Power-Up
Upon power-up, the MAX5128 updates the wiper position with the data stored in the nonvolatile memory. This initialization period takes 2s (typ). For proper operation, limit the supply voltage slew rate to 10s.
Applications Information
Use the MAX5128 for applications requiring digitally controlled adjustable resistance or voltage, such as LCD contrast control (where voltage biasing adjusts the display contrast), or DC-DC converters with adjustable outputs. The 22k end-to-end resistance is divided into 128 tap points of 172 each. Use the MAX5128 in a voltage-divider or variable-resistor configuration.
LED Bias Adjustment
Figure 8 shows a LED bias adjustment application using a MAX5128 to set the current of the LEDs that the MAX1574 drives. Use the MAX5128 for an adjustable LED current drive of 10mA to 60mA.
Chip Information
PROCESS: BiCMOS
VCOM Generator
Figure 5 shows an application using the MAX4238 and the MAX5128 to generate the VCOM voltage for a LCD panel. Adjusting the resistor value of the MAX5128 changes the VCOM voltage. Adjusting the VCOM voltage changes the contrast for the LCD panel.
