Description

The WM8816 is a highly linear stereo volume control foraudio systems. The design is based on resistor chains withexternal op-amps, which provides flexibility for the supplyvoltage, signal swing, noise floor and cost optimisation. Thegain of each channel can be independently programmedfrom -111.5dB to +15.5dB through a digital serial controlinterface.

Audible clicks on gain changes are eliminated by changinggains only when a zero crossing has been detected in thesignal. The device also features peak level detection, whichcan be used for Automatic Gain Control. The WM8816operates from a single +5V supply and accepts signal inputlevels up to ±18V.

The WM8816 is available in a 16-pin SOIC package. It isguaranteed over a temperature range of -40° to 85°C.
