General 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.

Overview

DESCRIPTION The WM8816 is a highly linear stereo volume control for audio systems.

Key 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. WM8816 Stereo Digital Volume Control Advanced Information, September 2000, Rev 1.1.
