Overview
The AD5207BRUZ10, produced by Analog Devices Inc., is a dual-channel, 256-position digitally controlled variable resistor (VR) device. This component functions as a digital potentiometer, offering the same electronic adjustment capabilities as traditional potentiometers or variable resistors. Each channel of the AD5207 contains a fixed resistor with a wiper contact that can be programmed via a 3-wire SPI-compatible serial data input and output interface. This device is suitable for various applications requiring precise and programmable resistance adjustments.
