1 9-956; Rev 3; /5 32-Tap FleaPoT, 2-ire Digital General Description The linear-taper digital potentiometers perform the same function as a mechanical potentiometer or a variable resistor. These devices consist of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a 2-wire serial interface. The MAX5462/MAX5465/MAX5468 are configured as potentiometers. The rest of the devices in this family are configured as variable resistors. See Pin Configurations for part functionality. Three resistance values are available: kω (MAX5466/ /MAX5468), 5kΩ (MAX5463/MAX5464/ MAX5465), and kω (MAX546//MAX5462). The MAX546 MAX5465 (kω and 5kΩ) are available in space-saving 5-pin and 6-pin SC7 packages. The MAX5466//MAX5468 (kω) are available in 5-pin and 6-pin SOT23 packages.

5 Detailed Description The consist of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a 2-wire serial interface. Three resistance values are available: kω (MAX5466// MAX5468), 5kΩ (MAX5463/MAX5464/MAX5465), and kω (MAX546//MAX5462). The MAX5462/MAX5465/MAX5468 are designed to operate as potentiometers. In this configuration, the low terminal of the resistor array is connected to ground (pin 2). The /MAX5464/ perform as variable resistors. In these devices, the wiper terminal and high terminal of the resistor array are connected at pin 5. The MAX546/MAX5463/MAX5466 are similar variable resistors, except the low terminal is connected to ground (pin 2). Digital Interface Operation The have two modes of operation when the serial interface is active: increment and decrement mode. The serial interface is only active when is low. The and inputs control the position of the wiper along the resistor array. hen transitions from high to low, the part will go into increment mode if is high, and into decrement mode if is low. Once the mode is set, the device will remain in that mode until goes high again. A low-to-high transition at the pin will increment or decrement the wiper position depending on the current mode (Figures and 2). hen the input transitions to high (serial interface inactive), the value of the counter is stored and the wiper position is maintained. Note that when the wiper reaches the maximum (or minimum) tap position, the wiper will not wrap around to the minimum (or maximum) position. t CU t IC t IL t CI t IH t SETTLE t SETTLE NOTE: "" IS NOT A DIGITAL SIGNAL.

6 Power-On Reset All parts in this family feature power-on reset (POR) circuitry that sets the wiper position to midscale at powerup. By default, the chip is in the increment mode. Applications Information The are intended for circuits requiring digitally controlled adjustable resistance, such as LCD contrast control, where voltage biasing adjusts the display contrast. Controlling a Switch-Mode LCD Bias Generator Figure 3 shows an application where the variable resistor is used with a MAX77 to make an adjustable positive LCD-bias circuit. The output of the MAX77 is a positive voltage that is digitally controlled through the /MAX5464/. Similarly, Figure 4 shows the application of the variable resistor in a digitally controlled negative LCD-bias circuit along with the MAX774/MAX775/MAX776. Alternative Positive LCD Bias Control Alternatively, use an op amp to provide buffering and gain to the output of the MAX5462/MAX5465/MAX5468. Connect the mechanical potentiometer to the positive input of a noninverting op amp (Figure 5) to select a portion of the input signal by digitally controlling the wiper terminal. Figure 6 shows a similar circuit for the /MAX5464/. Adjustable Gain Figure 7 shows how to use the variable resistor to digitally adjust the gain of a noninverting op amp configuration. Connect the /MAX5464/ in series with a resistor to ground to form the adjustable gain control of a noninverting amplifier. The MAX546 MAX5468 have a low 5ppm/ C ratiometric tempco that allows for a very stable adjustable gain configuration over temperature.
