AD7810YNZ

Overview

The AD7810YNZ 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 plastic dual-in-line package (PDIP). The component is specified for operation across a temperature range of –40 °C to +105 °C, ensuring reliability in industrial environments.

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.
• Portable handheld applications with strict power constraints.
• Battery-powered communications systems.

Procurement Notes

Verify the specific ordering suffix YNZ confirms the PDIP-8 package variant. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Check current availability status as legacy components may have limited stock or end-of-life notifications. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a low-pin-count ADC with integrated tracking is required. Consider the automatic power-down feature for battery-operated designs needing extended life. Verify that the serial interface timing aligns with the host microcontroller's capabilities. Ensure the input voltage range matches the application's signal levels relative to the reference voltage.

Part Context

The AD7810 belongs to Analog Devices' family of low-power, high-speed ADCs designed for space-constrained applications. It offers a compact solution by integrating the SAR core, clock oscillator, and serial port into a minimal footprint. This series is often utilized in portable instrumentation where board real estate and power efficiency are critical design parameters.

Replacement Considerations

Check for AD7810YR (SOIC-8) or AD7810YRM (microSOIC-8) if package form factor changes are acceptable. Verify pin compatibility before substituting surface-mount variants for through-hole designs.
