Overview

Description

The AD8403ARZ10 is a quad-channel, 10-bit digital potentiometer from Analog Devices. It features non-volatile memory, retaining settings during power-off. Each channel offers 10 kΩ resistance with 256 tap points, providing precise digital control over resistance values.
Key features:
- SPI-compatible interface for easy microcontroller communication.
- Low power consumption (typically 3 μA standby).
- ±1% resistor tolerance for accuracy.
- Single-supply operation (2.7V–5.5V).
Applications include gain adjustment, calibration, and programmable filters. The AD8403ARZ10 is ideal for systems requiring repeatable, digitally controlled resistance without mechanical potentiometers.
Package: 24-lead SOIC.
For detailed specs, refer to the datasheet.
