The AD8402ARUZ10 is a dual-channel, 256-position digital potentiometer designed as an electronic replacement for mechanical potentiometers and variable resistors. It provides two independent variable resistors with linear taper and a nominal resistance of 10 kΩ. The device is controlled through a 3-wire SPI-compatible serial interface and supports data update rates up to 10 MHz.
The part operates from a single 2.7 V to 5.5 V supply and includes a power shutdown mode drawing less than 5 μA. Key electrical specifications include ±20% resistance tolerance, 200 Ω typical wiper resistance, 500 ppm/°C temperature coefficient, and ±1% channel-to-channel matching tolerance. The memory type is volatile, so wiper settings are not retained after power is removed.
Typical applications include mechanical potentiometer replacement, programmable filters, delays, time constants, volume control, line impedance matching, and power supply adjustment. The AD8402ARUZ10 is available in a surface-mount 14-TSSOP (0.173", 4.40 mm width) package and operates over the automotive temperature range of -40°C to 125°C.
