AD5262:  +15 V or ±5 V, Dual-Channel, SPI Compatible, 256 Position Digital Potentiometer

Product Description

The AD5260 and AD5262 are 1- and 2-channel, 256 position, SPI interface digitally controlled, variable resistor (VR) devices. These parts operate from either a single +5 V to +15 V supply or a dual ±5 V supply, extending terminal voltage adjustment to these supply voltages. (Most industry digital potentiometers are limited to a 5 V operating range). These devices perform the same electronic adjustment function as a potentiometer or variable resistor while offering solid-state reliability and electronic packaging compactness. These devices are offered in the thin 1.1 mm height TSSOP 14- and 16-lead surface mount packages.

Features

  • AD5262 – 2-Channel (Independently Programmable)
  • 5 V to 15 V Single-Supply; ±5.5 V Dual-Supply Operation
  • Potentiometer Replacement 20 kΩ, 50 kΩ,
