Overview
The AD7357YRUZ-500RL7, produced by Analog Devices Inc., is a high-performance, dual, 14-bit successive approximation analog-to-digital converter (ADC). This device operates from a single 2.5 V power supply and is designed for high-speed, low-power applications. It features two ADCs, each preceded by a low noise, wide bandwidth track-and-hold circuit capable of handling input frequencies exceeding 110 MHz. The AD7357 is ideal for applications requiring simultaneous sampling and high throughput rates, making it suitable for various industrial, medical, and automotive systems.
