The AD73322L is a low cost, low power CMOS general purpose dual analog front end
The AD73322L is a low‑cost, low‑power CMOS dual analog front‑end designed for general‑purpose applications such as speech, telephony, and active sound control. It integrates two 16‑bit A/D converters and two 16‑bit D/A converters, each delivering 78 dB signal‑to‑noise ratio and programmable input/output gains.
A flexible serial SPORT interface allows cascading up to four dual codecs, and the device operates from a single 2.7 V to 3.3 V supply with typical power consumption of 50 mW. The part is offered in 28‑lead SOIC, 28‑lead TSSOP, and 44‑lead LQFP packages and supports temperature ranges from –40 °C to +105 °C.
