ADS7819UB

Analog To Digital Converters (ADC) Overview

The ADS7819UB is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a throughput rate of 800 kHz and features a standard ±2.5V input range. The device integrates a sample/hold circuit, an internal reference, and clock logic within a 28-pin SOIC package. It requires dual power supplies of +5V for digital/analog logic and -5V for the analog section. Key performance metrics include a minimum Signal-to-Noise and Distortion Ratio (SINAD) of 68 dB at a 250 kHz input frequency, with integral linearity error specified at ±1 LSB maximum.

Analog To Digital Converters (ADC) Feature Summary

12-bit resolution with 800 kHz sampling throughput
Integrated internal 2.5V reference voltage
Parallel data output with three-state drivers
Inherent overvoltage protection up to ±25V

Analog To Digital Converters (ADC) Applications

Industrial process control systems
Data acquisition modules
High-speed instrumentation

Analog To Digital Converters (ADC) Procurement Notes

The ADS7819UB is classified as an obsolete component by the manufacturer. Production has been discontinued, meaning new units are no longer available directly from the factory. Sourcing must rely on existing distributor stock or secondary market channels. Verify RoHS compliance status and original packaging details through authorized distributors before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component only if legacy compatibility with parallel interfaces and specific ±5V supply requirements is necessary. Ensure the design accommodates the 28-pin SOIC footprint. For new designs requiring similar performance, consider modern successors that offer lower power consumption and single-supply operation, as this part is no longer recommended for new applications.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS7819 family of high-speed CMOS analog-to-digital converters produced by Burr-Brown, now part of Texas Instruments. The 'UB' suffix denotes the industrial temperature grade (-40°C to +85°C) and the SOIC package variant. It shares architectural similarities with other SAR ADCs in the series but is distinguished by its specific parallel interface and dual-supply configuration.
