Description
The ADS1110A0IDBVT from Texas Instruments is a high-precision, continuously self-calibrating 16-bit Delta-Sigma Analog-to-Digital Converter (ADC) built for demanding measurement applications. Featuring an integrated 2.048V precision voltage reference, it provides a stable differential input range of ±2.048V. With an onboard Programmable Gain Amplifier (PGA) offering gains up to x8, the ADS1110 excels at capturing even the smallest input signals with exceptional resolution.
Engineered for power-sensitive environments, the device operates on a single supply (2.7V to 5.5V) and supports user-selectable conversion rates of 15, 30, 60, or 240 samples per second. Its smart “single-conversion” mode automatically powers down the ADC after each reading, significantly reducing power consumption during idle times. Housed in a compact 6-pin package, the ADS1110 is the ideal choice for high-accuracy sensor interfacing where board space and low power draw are critical.
