Product Details
The AD5122/AD5142 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 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 accurate resistor matching.
The high bandwidth and low total harmonic distortion THD ensure optimal performance for ac signals, making these devices suitable for filter design.
The low wiper resistance of only 40 Ω at the ends of the resistor array allows for pin to pin connection.
The wiper values can be set through an SPI-compatible digital interface that also reads back the wiper register and EEPROM contents.
The AD5122/AD5142 is 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.
