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 featuring two 16‑bit A/D converters and two 16‑bit D/A converters. It provides 78 dB signal‑to‑noise ratio for both ADC and DAC paths and supports programmable input/output sample rates up to 64 kHz.
The device operates from a single 2.7 V‑3.3 V supply, consumes about 50 mW at 3.0 V, and works over an industrial temperature range of –40 °C to +105 °C. Pin configurations, timing diagrams, absolute maximum ratings and ordering information are included for designers.
