The AD8402ARZ1 is a dual-channel digital potentiometer from Analog Devices, part of the AD8400/AD8402/AD8403 family. It features a resistance of 1 kOhm with 256 linearly tapered taps, controlled via a 3-wire SPI-compatible serial interface. The device operates from a single 2.7V to 5.5V supply and has volatile memory, meaning the wiper position is lost when power is removed.
This digital potentiometer is designed to replace mechanical potentiometers in a wide range of applications, including programmable filters, delays, time constants, volume control, and power supply adjustment. It offers a typical temperature coefficient of 700 ppm/°C and operates over the industrial temperature range of -40°C to 125°C.
The AD8402ARZ1 is housed in a 14-SOIC surface-mount package (0.154" width, 3.90mm body width) and is supplied in a tube or tape-and-reel format. The dual-channel configuration allows independent control of two variable resistors in a compact footprint.
The resistance is 1 kOhm.
It has 256 taps.
The supply voltage range is 2.7V to 5.5V.
The operating temperature range is -40°C to 125°C.
It is available in a 14-SOIC surface-mount package (0.154" width, 3.90mm body width).
RoHS compliance is listed as RoHS3 Compliant but is unverified.
It uses an SPI serial interface.
