ADS7810U

Analog To Digital Converters (ADC) Overview

The ADS7810U is a 12-bit, 800kHz sampling CMOS analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a standard ±10V input range and operates from dual ±5V power supplies. The device integrates a successive approximation register (SAR), sample/hold circuit, internal reference, and clock logic within a 28-pin SOIC package. Key electrical specifications include a throughput rate of 800kHz, a minimum signal-to-noise and distortion ratio (SINAD) of 69dB at a 250kHz input frequency, and integral/differential linearity errors of ±3 LSB. It utilizes parallel data output with latches and 3-state drivers.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'U' corresponds to the 28-pin SOIC plastic package variant. Confirm that the application supports dual ±5V supply requirements, as this component does not operate on single-supply configurations. Ensure ESD precautions are observed during handling due to the sensitivity of precision integrated circuits.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7810U when a high-speed, parallel interface ADC with a wide ±10V input range is required. It is suitable for applications needing an integrated solution without external clocks or references. Consider the ±5V dual supply constraint and the 28-pin footprint size relative to other available packages in the family.

Analog To Digital Converters (ADC) Part Context

The ADS7810U belongs to the ADS7810 series of high-speed CMOS ADCs. It is distinguished by its ability to handle large input signals directly without external attenuation networks, thanks to internal scaling resistors. The device is specified for operation over the industrial temperature range of -40°C to +70°C.
