Overview
The AD5235BRUZ25-EP-R7, manufactured by Analog Devices Inc., is a dual-channel, nonvolatile memory, digitally controlled potentiometer. This component offers a 1024-step resolution and is available in a 16-pin TSSOP package. It features a 3-wire serial control interface and supports both linear and logarithmic taper adjustments. The device includes extra EEPROM for user-defined information and has a power-on reset feature that loads the mid-scale position until new values are programmed by the user.
