Datasheet Summary
DESCRIPTION
The WM8816 is a highly linear stereo volume control for audio systems. The design is based on resistor chains with external op-amps, which provides flexibility for the supply voltage, signal swing, noise floor and cost optimisation. The gain of each channel can be independently programmed from -111.5dB to +15.5dB through a digital serial control interface.
Audible clicks on gain changes are eliminated by changing gains only when a zero crossing has been detected in the signal. The device also Features peak level detection, which can be used for Automatic Gain Control. The WM8816 operates from a single +5V supply and accepts signal input levels up to ±18V.
The WM8816 is...
