Overview
The AD73311ARSZ is a single-channel, 3 V and 5 V front-end processor designed for general-purpose applications, including speech and telephony. Developed by Analog Devices Inc., this component features a 16-bit A/D conversion channel and a 16-bit D/A conversion channel. Each channel provides a 70 dB signal-to-noise ratio over the voiceband signal bandwidth. The AD73311ARSZ is part of the AD73311 series, which includes variations such as the AD73311L, offering improved on-chip filtering and more sample-rate options at a lower cost.
