The AD73311L is a low cost, low power CMOS general purpose analog front end with 16-bit analog to digital converter (ADC) and 16-bit digital to analog converter (DAC). The AD73311L has a flexible serial interface that allows up to eight devices to be connected in cascade and supports single (+3 V) supply operation.
The AD73311L is a complete front‑end processor for general‑purpose analog I/O, speech processing, and telephony applications. It features 16‑bit A/D and D/A conversion channels, 70 dB signal‑to‑noise ratio, programmable gain, and a serial SPORT interface that supports cascading up to eight devices.
The device is supplied in 20‑lead SOIC, SSOP, and TSSOP packages, with detailed pin configurations and functional descriptions provided. Specifications cover ADC/DAC performance, timing characteristics, power consumption, and absolute maximum ratings, making it suitable for low‑power, single‑supply operation in a variety of audio and communication systems.
