Overview
The ADS1100A0IDBVR is a precision, self-calibrating 16-bit Analog-to-Digital (A/D) converter produced by Texas Instruments. This device is designed for high-resolution measurement applications where space and power consumption are critical. It features differential inputs, a Programmable Gain Amplifier (PGA) with gains up to 8, and an I2C-compatible serial interface. The ADS1100 operates from a single power supply ranging from 2.7V to 5.5V and can perform conversions at rates of 8, 16, 32, or 128 samples per second. Its compact SOT23-6 package makes it ideal for applications requiring minimal footprint and low power consumption.
