Description
The AD5204BRUZ100 is a quad digitally programmable potentiometer from Analog Devices. It provides four independent 100 kΩ end-to-end potentiometer sections (A–W terminals per channel) with 256 discrete wiper positions (8-bit resolution) per channel. Control is via a serial interface (I2C-compatible), enabling fast software updates of each channel’s wiper setting. Typical supply range is 2.7 V to 5.5 V, making it suitable for many analog and mixed-signal circuits. The BRUZ suffix denotes the RoHS-compliant package and device family variant (16-lead package format). Applications include programmable gain/attenuation, sensor calibration, DC bias adjustment, and other adjustable-analog-dimension tasks in audio, instrumentation, and control systems. In short: a multi-channel, I2C-controlled digital potentiometer with precise, programmable resistance for flexible analog tuning.
