ADS7816UB

Analog To Digital Converters (ADC) Overview

The ADS7816UB is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-channel differential input and operates with a sampling rate of 200 kS/s. The device utilizes an external reference voltage and communicates via a 3-wire serial interface compatible with SPI. It functions within an analog and digital supply voltage range of 4.5 V to 5.25 V. Key performance metrics include a signal-to-noise and distortion ratio (SINAD) of 72 dB, differential nonlinearity (DNL) of +/- 1 LSB, and integral nonlinearity (INL) of +/- 2 LSB. Power consumption is rated at 1.9 mW, and it supports operation from -40°C to +85°C in a VSSOP-8 package.
