AD7810YRZ-REEL

Overview

The AD7810YRZ-REEL is a 10-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single supply voltage ranging from 2.7 V to 5.5 V and features an inherent track-and-hold function with a maximum conversion time of 2.3 µs. The device utilizes a pseudo-differential input architecture and communicates via a high-speed serial interface compatible with standard SPI protocols. Designed for low-power applications, it supports automatic power-down modes that reduce consumption significantly at lower throughput rates. The component is specified for operation across a temperature range of –40 °C to +105 °C.

Feature Summary

• Integrates a 10-bit SAR ADC with built-in track-and-hold functionality in a compact package.
• Supports automatic power-down mode to minimize energy usage during low-throughput operations.
• Features a microcontroller-compatible serial interface requiring minimal external circuitry.
• Operates on a single supply voltage with flexible reference input options.

Applications

• Battery-powered test equipment requiring 10-bit accuracy.
• Portable communications systems with limited power budgets.
• Hand-held portable devices needing efficient analog-to-digital conversion.

Procurement Notes

Verify the specific ordering suffix REEL indicates tape-and-reel packaging when sourcing this component. Confirm that the Y version meets the required linearity specifications of ±1 LSB. Ensure the supplier provides documentation confirming compliance with RoHS standards for the intended manufacturing process.

Selection Notes

Select this model when a space-constrained design requires a complete 10-bit ADC solution without external references. Consider the automatic power-down feature if the application involves intermittent sampling at rates below 100 kSPS. Verify that the source impedance of the analog input signal is sufficiently low to meet the acquisition time requirements within the system timing constraints.

Part Context

This component belongs to the AD7810 family of low-power, high-speed ADCs. It shares architectural similarities with other members like the AD7811 and AD7812 but differs in channel count and pin configuration. The Y variant specifically denotes the SOIC package option within the broader product line designed for general-purpose data acquisition tasks.

Replacement Considerations

Direct replacements include the AD7810YNZ for DIP packaging or the AD7810YRMZ for microSOIC packaging. These variants maintain identical electrical characteristics and pinouts, differing only in the physical housing type selected for the assembly process.
