ADS1110A1IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1110A1IDBVR is a precision, continuous self-calibrating analog-to-digital converter (ADC) featuring a sigma-delta architecture and a single differential input channel. It delivers 16-bit resolution with an internal 2.048 V reference, enabling a ±2.048 V differential input range. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It supports I2C-compatible serial interfaces and offers programmable data rates of 15, 30, 60, or 240 samples per second. Integrated features include a programmable gain amplifier (PGA) with gains up to 8, an onboard oscillator, and automatic power-down in single-conversion mode. The component is housed in a compact SOT-23-6 package and functions within a temperature range of -40°C to +125°C.
