Analog Devices Inc. AD8403AR1 is a four-channel, 256-tap digital potentiometer with a nominal resistance of 1 kOhm. This volatile memory device features a linear taper and a typical resistance tolerance of ±33%. The AD8403AR1 operates with a supply voltage range of 2.7V to 5.5V and maintains functionality across an extended temperature range of -40°C to 125°C. Communication is facilitated via an SPI interface, allowing for precise digital control of resistance. The device includes a cascade pin for extending the number of taps. Packaged in a 24-SOIC (0.295" width) surface-mount configuration, this component is suitable for applications in industrial automation, medical equipment, and test and measurement systems requiring precise analog signal conditioning and level setting. The typical temperature coefficient is 700ppm/°C.
