AD7357 is a dual 14-bit SAR ADC with a maximum conversion rate of 4.2 MSPS and a 2.5 V supply voltage. It is packaged in a 16-lead TSSOP.
The AD7357 is a dual, 14‑bit, high‑speed, low‑power successive‑approximation ADC that operates from a single 2.5 V supply and provides up to 4.2 MSPS per channel. It features on‑chip 2.048 V reference, differential inputs, and a high‑speed serial interface compatible with SPI, QSPI, Microwire and DSP protocols.
The device is supplied in a 16‑lead thin‑shrink small‑outline package (TSSOP) and is rated for operation from –40 °C to +125 °C (Y‑grade). Detailed specifications, pin descriptions, timing, and layout recommendations are provided for designers.
