AD7812YRU

Overview

The AD7812YRU is an 8-channel, 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It operates from a single 2.7 V to 5.5 V supply and features a throughput rate of 350 kSPS with a conversion time of 2.3 µs. The device integrates an on-chip track-and-hold amplifier and a 2.5 V reference circuit. It utilizes a high-speed serial interface compatible with DSPs and microcontrollers. The Y version guarantees ±1 LSB differential nonlinearity and ±2 LSB gain error. It is housed in a 20-lead Thin Shrink Small Outline Package (TSSOP).

Feature Summary

Integrates an onboard 2.5 V reference circuit that powers down when an external reference is selected.
Supports hardware and software control for conversion start and power-down modes.
Features a package address pin allowing two devices to share the same serial bus in multipackage applications.

Applications

Automotive data acquisition systems
Industrial process control monitoring
Portable instrumentation

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and linearity specifications. Confirm availability status as distribution channels may vary. Ensure compatibility with system voltage requirements ranging from 2.7 V to 5.5 V before integration.

Selection Notes

Select this component for applications requiring multiple single-ended or pseudo-differential inputs with low power consumption. Consider the 350 kSPS sampling rate and 10-bit resolution for general-purpose signal conditioning. Verify serial interface timing constraints with the host processor.

Part Context

This part belongs to the AD7811/AD7812 family of 10-bit sampling ADCs. The AD7812 variant specifically provides eight input channels compared to the four channels in the AD7811. Both share identical architecture, power characteristics, and serial interface protocols.
