The AD73322 is a dual front-end processor for general-purpose applications including speech and telephony. It features two 16-bit A/D conversion channels and two 16-bit D/A conversion channels. Each channel provides 77ÊdB signal-to-noise ratio over a voiceband signal bandwidth. It also features an input-tooutput gain network in both the analog and digital domains. This is featured on both codecs and can be used for impedance matching or scaling when interfacing to Subscriber Line Interface Circuits (SLICs).
