ORDERING INFORMATION DS1808Z-050 16-Pin SOIC -40ºC to +85ºC 45kΩ DS1808Z-050/T&R 16-Pin SOIC -40ºC to +85ºC 45kΩ DESCRIPTION The DS1808 is a dual-channel, digitally controlled, log-taper potentiometer. Each potentiometer is comprised of 32 wiper terminal positions plus a mute position. The device has three accessible potentiometer terminals that include the high-side terminal (H), the low-side terminal (L), and the wiper terminal (W) ...
