Overview
The ADS1100A2IDBVT is a precision, continuously self-calibrating Analog-to-Digital (A/D) converter produced by Texas Instruments. It features differential inputs and up to 16 bits of resolution, packaged in a small SOT23-6 package. The device performs conversions ratiometrically using the power supply as the reference voltage and operates from a single power supply ranging from 2.7V to 5.5V. It is designed for applications requiring high-resolution measurement, where space and power consumption are critical factors.
