AD8400AR1 Description

Short technical summary and product information.

The AD8400AR1 is a single-channel, 256-position digital potentiometer from Analog Devices. It features an end-to-end resistance of 1 kOhm with a linear taper, controlled via a 3-wire SPI-compatible serial interface. The device operates from a single 2.7V to 5.5V supply and is designed for surface-mount applications in an 8-SOIC package.

 

This volatile digital potentiometer replaces mechanical potentiometers in a variety of applications, including programmable filters, delays, time constants, volume control, and power supply adjustment. The wiper position is set by a digital code loaded into the serial input register and is lost upon power-down.

 

The AD8400AR1 is specified for an operating temperature range of -40°C to 125°C, making it suitable for industrial and automotive environments. The part is available in tape and reel packaging.
