Description
AD5142BRUZ100 is a dual channel, 256 position, SPI interface, non-volatile digital potentiometer. It offers guaranteed low resistor tolerance errors of ±8% and upto ±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 accurate resistor matching. The high bandwidth and low total harmonic distortion ensure optimal performance for ac signals, making this device suitable for filter design. The low wiper resistance of only 40 ohm at the ends of the resistor array allows pin to pin connection. Applications include portable electronics level adjustment, LCD panel brightness and contrast controls, programmable filters, delays, and time constants, programmable power supplies.
