AD5142 Datasheet (ad5122 / Ad5142) Nonvolatile Digital Potentiometer

Manufacturer: Analog Devices

Overview: Dual Channel, 128-/256-Position, SPI, Nonvolatile Digital Potentiometer Data.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The AD5122/AD5142 potentiometers provides a nonvolatile solution for 128-/256-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the Ax, Bx, and Wx pins.

The low resistor tolerance and low nominal temperature coefficient simplify open-loop applications as well as applications requiring tolerance matching.

The linear gain setting mode allows independent programming of the resistance between the digital potentiometer terminals, through the RAW and RWB string resistors, allowing very accurate resistor matching.

Key Features

  • 10 kΩ and 100 kΩ resistance options Resistor tolerance: 8% maximum Wiper current: ±6 mA Low temperature coefficient: 35 ppm/°C Wide bandwidth: 3 MHz Fast start-up time < 75 µs Linear gain setting mode Single- and dual-supply operation Independent logic supply: 1.8 V to 5.5 V Wide operating temperature:.
