Description
AD8402ARUZ1 is a dual digital potentiometer from Analog Devices (AD8400 family). It contains two programmable potentiometers in one package and is controlled by a serial digital interface (SPI/I2C-compatible). Use it to provide adjustable attenuation, gain, or calibration in analog signal paths. The ARUZ1 suffix indicates a specific RoHS-compliant packaging variant. For exact specs (end-to-end resistance, number of taps, supply range, memory behavior), consult the AD8402 datasheet.
Features
AD8402ARUZ1 is a dual digitally controlled potentiometer with the following typical features:
- Two 256-position pots (8-bit resolution)
- I2C-compatible serial control interface
- End-to-end resistance per pot (nominal value available in device variants)
- Wiper registers: both volatile and nonvolatile memory (stores last setting)
- Wide supply range (approximately 2.7 V to 5.5 V)
- Low quiescent current with power-down option
- Industrial temperature range (-40°C to +125°C)
- RoHS-compliant, compact package (ARUZ1 variant)
Note: exact end-to-end resistance values and package details should be confirmed in the specific datasheet revision for AD8402ARUZ1.
