AD7813YNZ

Overview

The AD7813YNZ is a high-speed, microprocessor-compatible analog-to-digital converter featuring a 10-bit resolution and a maximum throughput of 400 kSPS. It operates from a single supply voltage ranging from 2.7 V to 5.5 V and incorporates an on-chip track-and-hold circuit, clock oscillator, and successive approximation architecture. The device utilizes an 8-bit wide parallel interface with three-state drivers, requiring two read operations to retrieve the full 10-bit result. It supports automatic power-down modes to minimize energy consumption at lower sampling rates.

Feature Summary

• Integrates a charge redistribution DAC with on-chip track-and-hold circuitry for signal acquisition.
• Features an 8-bit parallel interface designed for direct connection to microprocessors and DSPs.
• Includes an internal clock oscillator and logic control for simplified system integration.

Applications

• Microprocessor-based data acquisition systems
• Battery-powered instrumentation utilizing automatic power-down modes
• Industrial process control applications

Procurement Notes

Verify component authenticity through authorized Analog Devices distribution channels. Confirm package integrity and pin alignment against the 16-lead plastic dual-in-line specification. Ensure storage conditions comply with electrostatic discharge precautions due to device sensitivity.

Selection Notes

Select this model when a 10-bit resolution and 400 kSPS throughput are required within a single-supply environment. Consider the DIP-16 package for through-hole mounting requirements. Evaluate power consumption profiles if operating at low throughput rates where automatic power-down features provide efficiency benefits.

Part Context

This component belongs to the AD7813 series of sampling analog-to-digital converters manufactured by Analog Devices Inc. The series includes variants such as the AD7819 (8-bit) and other packaging options like SOIC and TSSOP. The YNZ suffix specifically denotes the 16-lead plastic dual-in-line package configuration.

Replacement Considerations

The AD7819YNZ serves as a compatible alternative offering 8-bit resolution within the same package and interface specifications. Verify that the reduced resolution meets application accuracy requirements before substitution.
