LP digital potentiometers with max ±8% resistance tolerance

Analog Devices, Inc. (ADI), has introduced a series of single-channel digital potentiometers that provide a variety of resolution, interface and resistance options.

ADI says the AD511x series of digital potentiometers provides excellent resistance tolerance, high current density and faster nonvolatile memory than competing devices and are also low power and easy-to-use.

Key features of AD511x digital potentiometer series include:
Single channel, 128-/64-/32-tap digital potentiometers
5k ohm, 10k ohm, 80k ohm nominal resistance options
I2C, Up/Down and Push-Button interfaces
Maximum ±8% nominal resistance tolerance
5 ppm/°C Temperature Coefficient (potentiometer mode)
Low power: Idd = 750nA typical
-40°C to +125°C operating temperature range
