Overview
The ADS1100A1IDBVT, produced by Texas Instruments, is a precision, continuously self-calibrating 16-bit Analog-to-Digital (A/D) converter. It features differential inputs and is packaged in a small SOT23-6 package, making it ideal for applications where space and power consumption are critical. The device operates from a single power supply ranging from 2.7V to 5.5V and uses an I2C-compatible serial interface for communication. The onboard Programmable Gain Amplifier (PGA) allows for gains of up to 8, enabling the measurement of smaller signals with high resolution.
