描述 Description

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.FEATURES
