AD7357 is a dual-channel 14-bit SAR ADC that features differential input, dual simultaneous sampling, and a throughput rate of 4.25 MSPS. It has low power dissipation, an on-chip reference voltage, and a high-speed serial interface.
The AD7357 from Analog Devices is a dual 14‑bit successive‑approximation SAR ADC with simultaneous sampling. It operates from a 2.5 V supply, provides an on‑chip 2.048 V reference, and is available in a 16‑lead TSSOP package.
The device delivers a maximum throughput of 4.25 MSPS per channel while consuming only 35 mW in normal mode. It supports a wide input bandwidth of 200 MHz and operates over a temperature range of –40 °C to +125 °C (Y grade).
