19-3665; Rev 0; 5/05 KIT ATION EVALU E L B AVAILA One-Time Programmable, Linear-Taper Digital Potentiometers The MAX5527/MAX5528/MAX5529 linear-taper digital potentiometers perform the same function as mechanical potentiometers, replacing the mechanics with a simple 2-wire up/down digital interface. These digital potentiometers provide an optional one-time programmable feature that sets the power-on reset position of the wiper. Once the wiper position is programmed, the 2-wire interface can be disabled to prevent unwanted adjustment. The MAX5527/MAX5528/MAX5529 provide an end-to-end resistance of 100k, 50k, and 10k, respectively. The devices feature low temperature coefficients of 35ppm/C end-to-end and 5ppm/C ratiometric. All devices offer 64 wiper positions and operate from a single +2.7V to +5.5V supply. An ultra-low, 0.25A (typ) standby supply current saves power in battery-operated applications. The MAX5527/MAX5528/MAX5529 are available in 3mm x 3mm, 8-pin TDFN and 5mm x 3mm, 8-pin MAX(R) packages. Each device is guaranteed over the -40C to +105C temperature range.

A high-to-low CS transition determines the increment/decrement mode. Increment if U/D is high, or decrement if U/D is low. CS is also used for one-time programming. See the PV OneTime Programming section. 3 VDD Supply Voltage. Bypass with a 0.1F capacitor to GND. 4 GND Ground 5 PV One-Time Programming Voltage. Connect PV to an 11V supply at the time the device is programmed/locked, and bypass with a 22F capacitor to GND. For normal operation, connect to GND or leave floating. 6 U/D Up/Down Control Input. When CS is low, a low-to-high transition at U/D increments or decrements the wiper position. See the Digital Interface Operation section. 7 L Resistor Low Terminal 8 H Resistor High Terminal Detailed Description The MAX5527/MAX5528/MAX5529 100k/50k/10k end-to-end resistance digitally-controlled potentiometers offer 64 wiper tap positions accessible along the resistor array between H and L. These devices function as potentiometers or variable resistors (see Figure 1). The wiper (W) position is adjusted sequentially through the tap positions using a simple 2-wire up/down interface. These digital potentiometers provide an optional one-time programmable feature that sets and locks the power-on reset position of the wiper (see the PV OneTime Programming section). Once the desired wiper position is programmed, the 2-wire interface can be disabled to prevent unwanted adjustment. Digital Interface Operation The MAX5527/MAX5528/MAX5529 provide two modes of operation when the serial interface is active: increment mode or decrement mode. The serial interface is only active when CS is low. The CS and U/D inputs control the position of the wiper along the resistor array. Set U/D high to increment the MAX5527/MAX5528/MAX5529 when CS transitions from high to low (Figure 2). Set U/D low to decrement the MAX5527/MAX5528/MAX5529 when CS transitions high to low (Figure 3). Once CS is held low, each lowto-high transition at U/D increments or decrements the wiper one position. Once the increment or decrement mode is set, the device remains in that mode until CS goes high. POTENTIOMETER CONFIGURATION VARIABLE-RESISTOR CONFIGURATION H H W W L L Figure 1. Potentiometer/Variable-Resistor Configuration Idle U/D high for normal operation. If U/D is low when CS transitions low to high, the wiper moves one additional tap in its present direction. The wiper remains in the same position when U/D is high and CS transitions low to high. After CS returns high, the wiper position remains the same (Figure 4). Additional increments do not change the wiper position when the wiper is at the maximum end of the resistor array. Additional decrements do not change the wiper position when the wiper is at the minimum end of the resistor array. _______________________________________________________________________________________ 7 MAX5527/MAX5528/MAX5529 Pin Description MAX5527/MAX5528/MAX5529 One-Time Programmable, Linear-Taper Digital Potentiometers VDD tUP CS tCU tCI tIL tIH tIC U/D tIW VW Figure 2.

Connect PV to GND or leave floating to continue powering up the wiper position at midscale.

PV Power-Supply Decoupling Change the wiper's power-up position using the PV one-time programming sequence after power-up (see Figure 5). After setting the wiper to the desired powerup position, perform the following six-step sequence: 1) 2) Set U/D and CS high. Connect an external voltage source at PV in the range of +11V to +11.55V. 3) 4a) Pull CS low. Pulse CS high for six cycles, consisting of CS starting low and going high for at least tCH, and then low for at least t CL , to change the wiper power-up position. The wiper remains adjustable. Pulse CS high for seven cycles, consisting of CS starting low and going high for at least tCH and then low for at least tCL, to change the wiper power-up position and lock the wiper in that same position. The seventh CS pulse is labeled the optional lockout bit in Figure 5. Connect PV to GND or release the voltage source, leaving PV floating. Pull CS high. 4b) 5) 6) Pulse CS high for six cycles to change the wiper powerup position. The wiper position returns to this programmed position on power-up, but remains adjustable. Pulse CS high for seven cycles to lock the MAX5527/ MAX5528/MAX5529 to a specific wiper position with no further adjustments allowed. This effectively converts the potentiometer to a fixed resistor-divider. The seventh pulse locks the wiper position and disables the up/down interface. Once locked, connect U/D and CS high, low, or leave them floating without increasing the supply current (see Table 1). The external PV power supply must source at least 5mA and have a good transient response. Decouple the PV power supply with a 22F capacitor to GND. Ensure that no more than 250H of inductance and/or 40 of parasitic resistance exists between the capacitor and the device (see Figure 6). _______________________________________________________________________________________ 9 MAX5527/MAX5528/MAX5529 One-Time Programmable, Linear-Taper Digital Potentiometers 5V 5V H 30V 30V W MAX5527 MAX5528 MAX5529 VOUT VOUT H MAX5527 MAX5528 MAX5529 L W L Figure 7.

Programmable Filter Applications Information Use the MAX5527/MAX5528/MAX5529 in applications requiring digitally controlled adjustable resistance, such as LCD contrast control where voltage biasing adjusts the display contrast, or for programmable filters with adjustable gain and/or cutoff frequency. Positive LCD Bias Control Figures 7 and 8 show an application where the voltagedivider or variable resistor is used to make an adjustable, positive LCD bias voltage. The op-amp provides buffering and gain to the resistor-divider network made by the potentiometer (Figure 7), or to a fixed resistor and a variable resistor (Figure 8).

Adjustable Voltage Reference Programmable Filter Figure 9 shows the configuration for a 1st-order programmable filter. The gain of the filter is adjusted by R2, and the cutoff frequency is adjusted by R3. Use the following equations to calculate the gain (G), and the -3dB cutoff frequency (fC), only up to frequencies one decade below the wiper -3dB bandwidth.

Bypass VDD with a 0.1F capacitor as close to the device as possible. When programming the wiper position, bypass PV with a 22F capacitor as close to the device as possible. For a VDD power supply with a slew rate greater than 1V/s or in applications where power-supply overshoot is prevalent, connect a 10 resistor in series to VDD and bypass VDD with an additional 4.7F capacitor to ground.
