Overview

Description

The AD8402ARZ100 is a dual-channel, 256-position digital potentiometer from Analog Devices. It features 100 kΩ resistance per channel and operates with a 2.7V to 5.5V supply, making it suitable for low-power applications.
Key features:
- SPI-compatible interface for easy digital control.
- Non-volatile memory retains settings when powered off.
- Low temperature coefficient (35 ppm/°C) ensures stable performance.
- ±1% resistor tolerance for precise adjustments.
Applications include volume control, LCD contrast adjustment, and programmable gain amplifiers. Its compact SOIC-14 package makes it ideal for space-constrained designs.
