APPLICATIONS
Mechanical potentiometer replacement Programmable filters, delays, time constants Volume control, panning L.
The AD8400/AD8402/AD8403 provide a single-, dual-, or quad-channel, 256-position, digitally controlled variable resistor (VR) device.1 These devices perform the same electronic adjustment function as a mechanical potentiometer or variable resistor. T.
