Product Overview

The AD5144BRUZ10 is a quad-channel Digital Potentiometer provides a nonvolatile solution for 256-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6mA 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. The high bandwidth and low THD ensure optimal performance for AC signals, making this device suitable for filter design. The low wiper resistance of only 40Ω at the ends of the resistor array allow for pin-to-pin connection. The wiper values can be set through a SPI-compatible digital interface that is also used to read back the wiper register and EEPROM contents.
