AD5204BRUZ100

The AD5204BRUZ100 is a 4-channel digital potentiometer from Analog Devices, offering 256 tap positions per channel with a nominal resistance of 100kΩ. It uses a 3-wire SPI-compatible serial interface for digital control, enabling precise resistance adjustment across all channels. The device features a linear taper and supports both single-supply (2.7V to 5.5V) and dual-supply (±2.3V to ±2.7V) operation. Key electrical characteristics include a typical -3dB bandwidth of 721 kHz, a low supply current of 12 µA, and a temperature coefficient of 700 ppm/°C. The resistance tolerance is ±30%, and the memory type is volatile, with power-on midscale preset. The IC includes cascade pins and selectable address pins for daisy-chaining multiple devices. It comes in a 24-lead TSSOP package with tin, matte contact plating, suitable for surface mount assembly. The operating temperature range spans -40°C to 85°C. Typical applications include replacing mechanical potentiometers in instrumentation for gain and offset adjustment, programmable filters, delays, time constants, and line impedance matching.
