The Analog Devices Inc./Maxim Integrated DS1859B-050 is a dual-channel digital potentiometer featuring 256 taps per channel, offering linear taper and a total resistance of 50k Ohms. This component utilizes a 2-wire serial interface (I2C) for control and includes a selectable address for multi-device configurations. The DS1859B-050 is packaged in a 16-CSBGA (4x4) surface-mount configuration and operates within a voltage supply range of 2.85V to 5.5V. Its non-volatile memory ensures memory retention across power cycles, and it incorporates a temperature sensor for environmental monitoring. Typical applications for this device include industrial control systems, medical instrumentation, and consumer electronics where precise, digitally controlled resistance adjustment is required. It operates across an industrial temperature range of -40°C to 95°C.
