AD7810YRMZ

Overview

The AD7810YRMZ 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. 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 logic.
• Pseudo-differential input scheme enables offset cancellation within the system.

Applications

• Battery-powered test equipment requiring 10-bit accuracy
• Portable handheld instrumentation
• Battery-powered communications systems

Procurement Notes

Verify the specific ordering suffix RMZ corresponds to the 8-lead microSOIC package variant. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the source documentation matches the REV B datasheet specifications for electrical parameters. Check for any specific handling requirements related to the small outline package during soldering.

Selection Notes

Select this component when a low pin count solution is required for 10-bit conversion tasks. Consider the automatic power-down feature if battery life is critical in portable designs. Evaluate the source impedance requirements, as high impedance may impact acquisition time and total harmonic distortion performance. Verify compatibility with the host microcontroller's serial clock speeds and logic levels.

Part Context

The AD7810 series includes variants such as the AD7810YNZ (DIP-8) and AD7810YRZ (SOIC-8). The YRMZ suffix specifically denotes the microSOIC package option. All variants share identical electrical characteristics and functionality, differing only in physical footprint and mounting style. This family is designed for space-constrained applications requiring efficient analog-to-digital conversion.

Replacement Considerations

Direct pin-for-pin replacements include other AD7810 variants like AD7810YRZ or AD7810YNZ depending on package preference. Cross-brand alternatives should be evaluated for matching resolution, sampling rate, and supply voltage ranges. Ensure any substitute supports the same serial interface protocol and pseudo-differential input configuration.
