AD7810YN

Analog To Digital Converters (ADC) Overview

The AD7810YN 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 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 supports automatic power-down modes, achieving low power consumption at lower throughput rates. The component is specified for operation across a temperature range of –40 °C to +105 °C and is housed in an 8-lead plastic dual-in-line package.

All variants share identical electrical characteristics and functional block diagrams, differing only in physical packaging dimensions.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include AD7810YR and AD7810YRM. Verify package footprint compatibility when substituting between DIP, SOIC, and microSOIC formats.

Analog To Digital Converters (ADC) FAQ

How does the AD7810 achieve low power consumption?

It employs an automatic power-down mode where the device powers down at the end of a conversion and wakes up for the next cycle, significantly reducing average power at lower throughput rates.

What is the input configuration of the AD7810?

The AD7810 features a pseudo-differential input structure consisting of VIN+ and VIN– pins, allowing for offset cancellation if needed.

Can the reference voltage be derived from the supply?

Yes, VREF can be connected directly to VDD to eliminate the need for an external reference voltage source, simplifying the design.
