GENERAL DESCRIPTION

The AD5122A/AD5142A potentiometers provide 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 linear gain setting mode allows independent programming

of the resistance between the digital potentiometer terminals,

through R_AWand R_WBthe string resistors, allowing very accurate

resistor matching.

The high bandwidth and low total harmonic distortion (THD)

ensure optimal performance for ac signals, making it suitable

for filter design.

LFCSP

The low wiper resistance of only 40 Ω at the ends of the resistor

array allows for pin-to-pin connection.

¹Two potentiometers and two rheostats.

The wiper values can be set through an I²C-compatible digital

interface that is also used to read back the wiper register and

EEPROM contents.

The AD5122A/AD5142A are available in a compact, 16-lead,

3 mm × 3 mm LFCSP and a 16-lead TSSOP. The parts are

guaranteed to operate over the extended industrial temperature

range of −40°C to +125°C.
