Overview
The AD7812YRUZ-REEL is a high-speed, low-power, 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single 2.7 V to 5.5 V supply and features a successive approximation ADC, an on-chip track/hold amplifier, and a 2.5 V on-chip reference. It also includes a high-speed serial interface compatible with most digital signal processors (DSPs) and microcontrollers. The AD7812 is particularly suited for applications requiring multiple input channels and high throughput rates.
