AD7810YRZ

Overview

The AD7810YRZ is a 10-bit successive approximation analog-to-digital converter (ADC) 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 conversion time of 2.3 µs maximum. 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 Small Outline Integrated Circuit (SOIC) 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 systems.
• Battery-powered communications systems.

Procurement Notes

Verify that the ordering suffix matches the required package type, as the YRZ designation corresponds specifically to the SOIC-8 variant. Confirm that the component meets RoHS compliance standards if environmental regulations apply to the assembly process. Ensure the supplier provides valid traceability documentation for the manufacturing lot to guarantee authenticity and quality control during integration.

Selection Notes

Select this component when a low pin count solution is required for space-constrained designs. It is suitable for applications where moderate speed and 10-bit resolution are sufficient. Consider the automatic power-down feature if battery life is critical. Verify that the source impedance of the analog signal is low enough to meet the acquisition time specifications for accurate conversion results.

Part Context

The AD7810 series includes variants such as the AD7810YNZ (DIP-8) and AD7810YRMZ (microSOIC-8). These parts share identical electrical characteristics but differ in physical packaging. The YRZ suffix specifically denotes the surface-mount SOIC package, distinguishing it from through-hole or smaller micro packages within the same product family.

Replacement Considerations

Direct replacements include other AD7810 variants like the AD7810YNZ or AD7810YRMZ, provided the package footprint is adaptable. Cross-family alternatives may require significant schematic redesign due to differences in pinout, interface protocols, or power requirements.
