AD7813YRUZ-REEL7

Overview

The AD7813YRUZ-REEL7 is a high-speed, microprocessor-compatible 8-/10-bit analog-to-digital converter manufactured by Analog Devices Inc. It features a maximum throughput of 400 kSPS and operates from a single 2.7 V to 5.5 V supply. The device integrates a 2.3 µs successive approximation A/D converter, track/hold circuitry, an on-chip clock oscillator, and an 8-bit wide parallel interface. It utilizes a TSSOP-16 package with a Reel shipping configuration. Key electrical parameters include a resolution of 10 bits, single-ended input type, SAR structure, DNL of +/- 1 LSB, INL of +/- 1 LSB, gain error of +/- 2 LSB, and power dissipation of 17.5 mW.

Feature Summary

• Microprocessor-compatible 8-bit parallel interface designed for easy integration with DSPs and microcontrollers using minimal external logic.
• Automatic power-down mode that significantly reduces power consumption at lower throughput rates by powering down after each conversion.
• On-chip track and hold circuitry combined with an internal clock oscillator eliminates the need for external timing components.

Applications

• Battery-powered instrumentation systems requiring low power consumption
• Industrial process control applications utilizing microprocessor interfaces
• Data acquisition systems interfacing with digital signal processors

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the Y version linearity specification meets the system accuracy requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-supply operation between 2.7 V and 5.5 V is required alongside a parallel data interface. Ensure the source impedance driving the VIN pin remains low enough to satisfy the 100 ns acquisition time constraint for optimal dynamic performance.
