AD8402AR1 Description

Short technical summary and product information.

The AD8402AR1 from Analog Devices is a dual-channel digital potentiometer offering 256 tap positions per channel. Each channel provides a variable resistance of 1 kΩ with linear taper. The device is controlled via a 3-wire SPI-compatible serial interface supporting data rates up to 10 MHz. It operates over a supply voltage range of 2.7V to 5.5V and features a power shutdown mode drawing less than 5 μA. The AD8402AR1 is designed for applications such as mechanical potentiometer replacement, programmable filters, and volume control. It is housed in a 14-SOIC surface-mount package with gull wing leads and operates over a temperature range of -40°C to +125°C. The temperature coefficient is 500 ppm/°C. The device is RoHS3 compliant and has an MSL of 1.
