Product Introduction

Overview

The AD7813YR, produced by Analog Devices Inc., is a high-speed, microprocessor-compatible, 8-/10-bit analog-to-digital converter (ADC). This device operates from a single supply voltage ranging from 2.7 V to 5.5 V and features a maximum throughput of 400 kSPS. The AD7813YR includes on-chip track and hold circuitry, a successive approximation A/D converter, and an on-chip clock oscillator. It also boasts an 8-bit wide parallel interface designed for easy interfacing with microprocessors and DSPs. The converter is particularly suited for applications requiring low power consumption and high-speed data conversion.

  • Parallel Interface: An easy-to-use 8-bit-wide parallel interface allows for easy interfacing to most popular microprocessors and DSPs with minimal external circuitry.
  • Dynamic Specifications: The AD7813YR is specified for ac parameters, including signal-to-noise ratio and distortion, making it suitable for DSP applications.

Applications

The AD7813YR is suitable for a variety of applications, including:

  • Battery-Powered Devices: The low power consumption and automatic power-down feature make it ideal for battery-powered applications.
  • Data Acquisition Systems: Its high-speed conversion and parallel interface make it a good fit for data acquisition systems requiring high throughput rates.
  • DSP and Microprocessor Systems: The device is designed to interface easily with most microprocessors and DSPs, making it a versatile component for various digital signal processing applications.
