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