ADS7805UE4

Analog To Digital Converters (ADC) Overview

The ADS7805UE4 is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates from a single +5V supply and features a standard ±10V input range with a minimum sampling rate of 100kHz. The device integrates a sample-and-hold circuit, internal reference, and clock logic within an SOIC-28 package. Key performance metrics include a maximum integral nonlinearity error of ±3 LSBs and a minimum signal-to-noise plus distortion ratio (SINAD) of 86 dB at a 20kHz input frequency. Power dissipation is specified at a maximum of 100mW.
