Part Details
- Wiper Position Stored in Nonvolatile Memory and Recalled Upon Power-Up
- Tiny SOT23 Package
- 35ppm/°C End-to-End Resistance Temperature Coefficient
- 5ppm/°C Ratiometric Temperature Coefficient
- 32 Tap Positions
- Voltage-Divider or Variable-Resistor Potentiometer Configuration
- 50kΩ and 100kΩ End-to-End Resistance Values
- 1µA (max) Static Supply Current
- 2.7V to 5.25V Single-Supply Operation
- 200,000 Wiper Store Cycles
- 50-Year Wiper Data Retention
The MAX5471/MAX5472/MAX5474/MAX5475 linear-taper digital potentiometers function as mechanical potentiometers, but replace the mechanics with a simple 3-wire up/down digital interface. These digital potentiometers feature nonvolatile memory (EEPROM) to return the wiper to its previously stored position upon power-up.
The MAX5471/MAX5472 are 2-terminal, variable resistors in 6-pin SOT23 packages. The MAX5474/MAX5475 are 3-terminal potentiometers in 8-pin SOT23 packages.
The MAX5471/MAX5474 have an end-to-end resistance of 50kΩ, and the MAX5472/MAX5475 have an end-to-end resistance of 100kΩ. All of these devices have 32 wiper positions, a low ratiometric temperature coefficient (5ppm/°C), and all operate from a single +2.7V to +5.25V supply. Each device is guaranteed over the extended -40°C to +85°C temperature range.
Applications
- Audio Volume Control
- Liquid-Crystal Display (LCD) Screen Adjustment
