Overview
Description
AD5220BRMZ100 is Analog Devices’ dual digitally controlled potentiometer (DCP). Each device contains two end-to-end resistive elements with independently adjustable wiper taps, set via a serial interface. The wiper positions provide programmable attenuation/gain for analog signals, enabling precise, repeatable adjustments without mechanical pots.
Key points:
- Dual DCPs: two programmable potentiometers in one package.
- Serial interface: SPI-compatible (chip-select, clock, data) to select a pot and set its wiper position.
- End-to-end resistance varies by variant (common values include 10 kΩ/50 kΩ/100 kΩ); Rab is set by the specific part.
- Packaging: BRMZ indicates an 8-pin surface-mount package (RoHS-compliant) in the MSOP/SOIC family.
- Voltage and power: operates from typical 2.7–5.5 V with low power consumption.
- Applications: sensor calibration, programmable gain/attenuation, offset tuning, audio/signal conditioning.
For exact Rab, word length, timing, and pinout, consult the AD5220 datasheet for the BRMZ100 variant.
