AD7810YRZ-REEL7

Overview

The AD7810YRZ-REEL7 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. Packaged in an 8-lead microSOIC format, it supports throughput rates up to 350 kSPS while maintaining low power consumption, which can be further minimized through automatic power-down modes at lower sampling frequencies.

Feature Summary

• Inherent track-and-hold functionality eliminates the need for external holding capacitors.
• 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 structure enables offset cancellation capabilities.

Applications

• Battery-powered test equipment requiring 10-bit accuracy
• Portable handheld applications with space constraints
• Battery-powered communications systems

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to tape-and-reel packaging when sourcing components. Confirm that the Y version meets the required linearity specifications of ±1 LSB across the full industrial temperature range. Ensure compatibility with existing PCB footprints for the 8-lead microSOIC package before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a balance between speed and power efficiency in a compact footprint. Consider the source impedance limitations during acquisition phases to maintain signal integrity. Evaluate whether the pseudo-differential input configuration aligns with the system's noise rejection requirements compared to fully differential alternatives.

Part Context

This part 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 interface types. The Y variant specifically denotes the industrial temperature grade and linearity performance within the broader product lineup.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to specific interface timing requirements. Verify electrical compatibility if substituting with other 10-bit SAR ADCs, particularly regarding serial clock speeds and power-up sequences.
