Analog Devices Inc./Maxim Integrated DS1666-50 is a single-circuit digital potentiometer with a nominal resistance of 50 kOhms. This component features 128 discrete tap positions, allowing for precise resistance adjustment through an Up/Down (U/D, INC, CS) serial interface. The DS1666-50 operates from a single 5V supply and is housed in a 14-PDIP package designed for through-hole mounting. Its volatile memory retains wiper position data while power is applied. The device offers a typical wiper resistance of 350 Ohms and a temperature coefficient of 750ppm/°C across its -40°C to 85°C operating temperature range. This digital potentiometer finds application in industrial automation, audio control, and general-purpose analog signal conditioning where precise, digitally controlled resistance is required.
