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.
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 sampling rates.
- Microcontroller-compatible serial interface allows direct connection without additional logic.
- Pseudo-differential input structure enables offset cancellation capabilities.
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 current manufacturer documentation to confirm package type and temperature grade. Confirm availability status as product lifecycles may change. Ensure compatibility with existing system voltage levels and serial communication protocols before integration.
Selection Notes
Select this component when a compact 10-bit ADC with low power consumption is required. Consider the pseudo-differential input if system offset cancellation is necessary. Verify that the microcontroller serial interface timing meets the setup and hold requirements defined in the datasheet specifications.
Part Context
The AD7810 series includes variants such as the AD7810YR (SOIC) and AD7810YRM (microSOIC). The AD7810YN specifically denotes the 8-lead plastic DIP package variant. All variants share identical electrical characteristics and functional block diagrams, differing only in physical packaging dimensions.
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.
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.
