Overview
The ADS1112IDGSRG4 is a precision, continuously self-calibrating Analog-to-Digital (A/D) converter produced by Texas Instruments. This component is designed to provide high-resolution measurements with up to 16 bits of resolution. It is available in small MSOP-10 and leadless QFN-style packages, making it ideal for applications where space and power consumption are critical. The ADS1112 features an onboard 2.048V reference, a programmable gain amplifier (PGA), and an onboard oscillator. It uses an I²C-compatible serial interface with eight pin-selectable addresses, allowing for flexible integration into various systems.
