The Texas Instruments ADS1110 is a precision, continuously self-calibrating analog-to-digital (A/D) converter featuring differential inputs and up to 16 bits of resolution. It is housed in a small SOT23-6 package and includes an onboard 2.048V reference, a programmable gain amplifier (PGA), and an onboard oscillator.
The device operates from a single power supply ranging from 2.7V to 5.5V and uses an I2C-compatible serial interface with eight available addresses. It supports data rates of 15, 30, 60, or 240 samples per second and is designed for applications requiring high-resolution measurement with minimal space and power consumption.
