AD7813YRZ-REEL

Overview

The AD7813YRZ-REEL is a high-speed, microprocessor-compatible 10-bit analog-to-digital converter manufactured by Analog Devices Inc. It features a maximum throughput of 400 kSPS and operates from a single supply voltage ranging from 2.7 V to 5.5 V. The device integrates a successive approximation architecture with an on-chip track-and-hold circuit and clock oscillator. It utilizes an 8-bit wide parallel interface for data output, requiring two read operations to retrieve the full 10-bit result. Power consumption is specified at 10.5 mW during normal operation at 3 V and drops to 34.6 µW in automatic power-down mode at 1 kSPS.

Feature Summary

• Integrates an on-chip clock oscillator and track-and-hold circuitry for simplified system design.
• Features an 8-bit wide parallel interface compatible with standard microprocessors and DSPs.
• Supports automatic power-down mode to significantly reduce average power consumption at lower sampling rates.

Applications

• Microprocessor-based data acquisition systems
• Battery-powered instrumentation
• Industrial process control

Procurement Notes

Verify that the REEL suffix corresponds to tape-and-reel packaging rather than tube packaging when sourcing this specific part number. Confirm the Y version designation indicates ±1 LSB linearity error. Ensure the component matches the SOIC-16 package outline required for your PCB layout.

Selection Notes

Select this component for applications requiring a balance between speed and low power consumption. The 400 kSPS rate suits moderate-speed signal processing. Verify that the external reference voltage range of 1.2 V to VDD aligns with your system's reference capabilities.

Part Context

This part belongs to the AD7813 family of 8-/10-bit sampling ADCs. It shares core specifications with variants like the AD7813YN and AD7813YRU but differs in physical packaging. The YRZ variant specifically denotes the narrow body small outline IC package.

Replacement Considerations

Publicly confirmed substitutes include the AD7813YN (Plastic DIP) and AD7813YRU (TSSOP). These parts share identical electrical characteristics but differ in package type.
