Overview
The AD7813YRUZ is a high-speed, microprocessor-compatible, 8-/10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates on a single supply voltage ranging from 2.7 V to 5.5 V and features a maximum throughput of 400 kSPS. It includes a successive approximation A/D converter, track/hold circuitry, an on-chip clock oscillator, and an 8-bit wide parallel interface, making it easy to interface with microprocessors and DSPs. The AD7813YRUZ is available in several package options, including a 16-lead plastic dual-in-line package (DIP), a 16-lead narrow body small outline IC (SOIC), and a 16-lead thin shrink small outline package (TSSOP).
