Product Overview
The ADS1100A0IDBVR is a self-calibrating, 16-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. Housed in a tiny SOT-23-6 package, it integrates a programmable gain amplifier (PGA) and an I2C interface, providing a complete data acquisition system in minimal board space. With its low power consumption of only 90µA and wide supply range of 2.7V to 5.5V, it is ideal for portable and battery-powered instrumentation.
