DESCRIPTION

· The TPL0202 is a dual-channel digital potentiometer with 256-tap resolution, featuring non-volatile memory for wiper settings storage.

· It offers a 10-kΩ end-to-end resistance and can operate as a three-terminal potentiometer or a two-terminal rheostat.

· Designed for digital control of resistance, it serves as a replacement for mechanical potentiometers.

FEATURES

· Two 256-position potentiometers with non-volatile memory for wiper settings.

· Fast power-up response time of less than 100µs and operates on a single supply from 2.7V to 5.5V.

· Features a SPI serial interface and operates over a temperature range from -40°C to +105°C.

· Low integral non-linearity (INL) and differential non-linearity (DNL) of ±1LSB and ±0.5LSB respectively in voltage-divider mode.

APPLICATIONS

· Used in adjustable gain amplifiers and offset trimming.

· Suitable for adjustable power supplies and precision calibration of setpoint thresholds.

· Ideal for sensor trimming and calibration, and as a mechanical potentiometer replacement.
