Part Details:

19-3067; Rev 1; 2/06 EVALUATION KIT AVAILABLE 32-Tap, Nonvolatile, Linear-Taper Digital Potentiometers in SOT23 MAX5471/MAX5472/MAX5474/MAX5475 General Description Features The MAX5471/MAX5472/MAX5474/MAX5475 linear- Wiper Position Stored in Nonvolatile Memory and taper digital potentiometers function as mechanical Recalled Upon Power-Up potentiometers, but replace the mechanics with a sim-ple 3-wire up/down digital interface. These digital Tiny SOT23 Package potentiometers feature nonvolatile memory (EEPROM) 35ppm/°C End-to-End Resistance Temperature to return the wiper to its previously stored position upon Coefficient power-up. 5ppm/°C Ratiometric Temperature Coefficient The MAX5471/MAX5472 are 2-terminal, variable resistorsin 6-pin SOT23 packages. The MAX5474/MAX5475 are 32 Tap Positions 3-terminal potentiometers in 8-pin SOT23 packages. Voltage-Divider or Variable-Resistor The MAX5471/MAX5474 have an end-to-end resistance Potentiometer Configuration of 50k, and the MAX5472/MAX5475 have an end-to-end resistance of 100k. All of these devices have 50k and 100k End-to-End Resistance Values 32 wiper positions, a low ratiometric temperature coeffi- 1µA (max) Static Supply Current cient (5ppm/°C), and all operate from a single +2.7V to+5.25V supply. Each device is guaranteed over the 2.7V to 5.25V Single-Supply Operation extended -40°C to +85°C temperature range. 200,000 Wiper Store Cycles 50-Year Wiper Data Retention Applications Mechanical Potentiometer Replacement Ordering Information Liquid-Crystal-Display (LCD) Screen Adjustment Audio Volume Control TEMP PKG PART PIN-PACKAGE RANGE CODE Programmable Filters M A X5 4 7 1 E Z T- T - 40° C to + 85° C 6 Thin SOT23-6 Z6-1 M A X5 4 7 2 E Z T- T - 40° C to + 85° C 6 Thin SOT23-6 Z6-1 M A X5 4 7 4 E KA- T - 40° C to + 85° C 8 SOT23-8
