Quality Control: Learn More
Analog Devices Inc./Maxim Integrated DS1802 is a dual-channel digital potentiometer featuring 65 taps per channel and a total resistance of 45k Ohms. This component offers logarithmic taper and ±20% tolerance, with a typical wiper resistance of 400 Ohms. The DS1802 supports a volatile memory type and operates across a voltage supply range of 2.7V to 5.5V. Key features include cascade pins for extended resistance ranges, a mute function, and zero-cross sensing. Control is achieved via a pushbutton and serial interface. Packaged in a 20-PDIP (0.300" width), it is suitable for through-hole mounting and operates within a temperature range of -40°C to 85°C. Applications span industrial automation, consumer electronics, and audio control systems.
