ADS1112IDRCRG4

Analog To Digital Converters (ADC) Overview

The ADS1112IDRCRG4 is a precision, continuous self-calibrating analog-to-digital converter (ADC) from Texas Instruments. It features a sigma-delta architecture with 16-bit resolution and supports two differential or three single-ended input channels. The device integrates an on-chip programmable gain amplifier (PGA) offering gains up to 8x and a 2.048V reference voltage, enabling a ±2.048V input range. It operates on a single 2.7V to 5.5V supply and communicates via an I²C-compatible serial interface with selectable addresses. Conversion rates are configurable at 15, 30, 60, or 240 samples per second (SPS). The component is housed in a compact VSSOP-10 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary
