AD7813YRZ-REEL7

Overview

The AD7813YRZ-REEL7 is a high-speed, microprocessor-compatible analog-to-digital converter manufactured by Analog Devices Inc. It features a 10-bit resolution with a maximum throughput of 400 kSPS and utilizes an 8-bit parallel interface. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical parameters include a signal-to-noise ratio of 58 dB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±1 LSB. Power consumption is specified at 17.5 mW during normal operation at 5 V, reducing significantly in automatic power-down modes.

Feature Summary

• Incorporates an on-chip successive approximation A/D converter with integrated track/hold circuitry and clock oscillator for simplified system design.
• Features an 8-bit wide parallel interface designed for direct connection to microprocessors and DSPs without complex external logic.
• Includes an automatic power-down mode that activates at the end of each conversion cycle to minimize average power consumption at lower sampling rates.

Applications

• Microprocessor-based data acquisition systems requiring fast sampling rates.
• Battery-powered instrumentation utilizing low-power automatic shutdown capabilities.
• Industrial control applications interfacing directly with digital signal processors.

Procurement Notes

Verify the specific package variant against the datasheet ordering guide, as the REEL7 suffix indicates tape-and-reel packaging distinct from tube configurations. Confirm that the Y version meets the required linearity specifications of ±1 LSB for your application. Ensure compatibility with the intended operating temperature range of -40°C to +105°C before finalizing procurement.

Selection Notes

Select this component when a single-channel, 10-bit ADC with a parallel interface is required for high-speed applications up to 400 kSPS. Consider the automatic power-down feature if battery life is critical at lower throughput rates. Verify that the source impedance of the analog input signal allows for the specified 100 ns acquisition time to maintain accuracy.

Part Context

This part belongs to the AD7813 series of 8-/10-bit sampling ADCs from Analog Devices. It shares functional similarities with other members of the family but differs in package options such as DIP, SOIC, and TSSOP. The YRZ designation specifically identifies the SOIC-16 package variant within this product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official cross-reference tools or contact technical support for verified alternatives compatible with the 10-bit SAR architecture and parallel interface requirements.
