AD7810YRMZ-REEL7

Overview

The AD7810YRMZ-REEL7 is a 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates on 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. It is housed in an 8-lead microSOIC package and is specified for operation across a temperature range of –40°C to +105°C.

Feature Summary

• Inherent track-and-hold functionality eliminates the need for external sampling circuits.
• Automatic power-down mode significantly reduces average power consumption at lower throughput rates.
• Microcontroller-compatible serial interface allows direct connection without additional glue logic.
• Pseudo-differential input scheme enables offset cancellation within the system.

Applications

• Battery-powered test equipment requiring 10-bit accuracy
• Hand-held portable applications with space constraints
• Battery-powered communications systems

Procurement Notes

Verify that the REEL7 suffix indicates tape-and-reel packaging suitable for automated surface-mount assembly. Confirm the Y variant meets the required linearity specifications and temperature range. Ensure the ordering quantity matches the reel capacity to avoid partial reel handling issues during production.

Selection Notes

Select this component when a compact 10-bit ADC with low power consumption is required. The automatic power-down feature makes it suitable for battery-operated devices where energy efficiency is critical. Verify that the serial interface timing aligns with the host microcontroller's capabilities.

Part Context

This part belongs to the AD7810 family, which includes variants in DIP and SOIC packages. The YRMZ designation specifically identifies the microSOIC package version with industrial temperature rating. Other family members may offer different pin counts or resolution levels but share similar architectural characteristics.

Replacement Considerations

Direct replacements include AD7810YNZ (DIP package) and AD7810YRZ (SOIC package). These alternatives maintain identical electrical performance but differ in physical footprint and mounting style. Verify PCB layout compatibility before substitution.
