Overview
The ADS1110A1IDBVR 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 includes an onboard 2.048V reference, a programmable gain amplifier (PGA), and an oscillator. It uses an I2C-compatible serial interface and operates from a single power supply ranging from 2.7V to 5.5V. The ADS1110 is designed for applications requiring high-resolution measurement, where space and power consumption are critical factors.
