Overview
The AD7475ARZ is a 12-bit, high-speed, low-power successive-approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single 2.7 V to 5.25 V power supply and is capable of throughput rates up to 1 MSPS when provided with a 20 MHz clock. It features a low noise, wide bandwidth track-and-hold amplifier and is housed in an 8-lead SOIC package, offering significant space-saving advantages. The AD7475ARZ is designed for applications requiring high-speed data acquisition with minimal power consumption.
