WM8816

Stereo Digital Volume Control

Advanced Information, September 2000, Rev 1.1

DESCRIPTION

FEATURES

•

Gain range from -111.5dB to +15.5dB

0.5dB Gain step size

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.

Total Harmonic Distortion 0.001% (100dB) typical

Crosstalk -110dB typical

Input signals up to ±18V

Zero Detection for Gain Changes

Hardware and Software Mute

Power On/Off Transient Suppression

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.

APPLICATIONS

•

Audio Amplifiers

The WM8816 is available in a 16-pin SOIC package. It is

guaranteed over a temperature range of -40° to 85°C.
