AD5263BRUZ20-REEL7

AD5263 is a quad-channel, 256-position, digital potentiometer with a selectable digital interface. This device performs the same electronic adjustment function as mechanical potentiometers or variable resistors, with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance. It is widely used in application such as mechanical potentiometer replacement, optical network adjustment, instrumentation: gain, offset adjustment, stereo channel audio level control, automotive electronics adjustment, programmable power supply, programmable filters, delays, time constants, line impedance matching, low resolution DAC/trimmer replacement, base station power amp biasing, sensor calibration etc.
