Analog Devices Inc./Maxim Integrated DS1802S- is a dual-channel digital potentiometer featuring 65 taps per channel with a total resistance of 45k Ohms. This component offers a logarithmic taper and a ±20% tolerance. The device supports a volatile memory type and operates from a 2.7V to 5.5V supply voltage. Key features include cascade pins for extended resistance ranges, a mute function, and zero-cross sensing capabilities. The interface is managed via a pushbutton and a serial communication protocol, simplifying integration into existing designs. With a typical temperature coefficient of 750ppm/°C and a wiper resistance of 400 Ohms, the DS1802S- is suitable for applications in industrial automation, consumer electronics, and test and measurement equipment. It is supplied in a 20-SOIC surface-mount package.
