AD7810YR

Overview

The AD7810YR is a 10-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 2.7 V to 5.5 V supply and features a conversion time of 2.3 µs maximum. The device includes an inherent track-and-hold function and interfaces via a high-speed serial port compatible with SPI, QSPI, and DSP standards. It supports pseudo-differential analog inputs ranging from 0 V to VREF. The component is specified for operation across a temperature range of –40°C to +105°C and is housed in an 8-lead Small Outline IC (SOIC) package.

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 architecture 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 the specific ordering suffix against the manufacturer's current documentation to confirm the package type and temperature grade. Ensure that the selected variant matches the required lead configuration and thermal specifications for the target application environment before finalizing procurement orders.

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 at low sampling rates. Verify that the source impedance driving the VIN+ pin is sufficiently low to meet acquisition time requirements, or utilize an external buffer amplifier to maintain signal integrity.

Part Context

The AD7810YR belongs to the AD7810 family of low-power, high-speed ADCs. This series offers multiple packaging options including microSOIC and DIP variants. The YR suffix specifically denotes the Small Outline IC (SOIC) package format, distinguishing it from other physical form factors within the same electrical specification set.

Replacement Considerations

Direct replacements include AD7810YN (Plastic DIP) and AD7810YRM (microSOIC). These parts share identical electrical characteristics but differ in physical package dimensions and mounting style. Verify footprint compatibility before substitution.
