The ADS1110 is a precision, continuously self-calibrating Analog-to-Digital (A/D) converter with differential inputs and up to 16 bits of resolution in a small SOT23-6 package. Its features include: onboard 2.048V reference, onboard PGA, onboard oscillator, 16-bit no missing codes, continuous self-calibration, single-cycle conversion, programmable data rate, I2C interface, power supply ranging from 2.7V to 5.5V, low current consumption, etc. It is suitable for applications such as portable instrumentation, industrial process control, smart transmitters, consumer goods, factory automation, temperature measurement, etc.
The ADS1110 is a precision, continuously self‑calibrating delta‑sigma A/D converter offered in a compact SOT23‑6 package. It provides up to 16‑bit resolution, programmable data rates from 15 SPS to 240 SPS, and an onboard 2.048 V reference. The device operates from a single supply of 2.7 V to 5.5 V and consumes only 240 µA in active mode, dropping to 0.05 µA in power‑down.
Typical applications include portable instrumentation, industrial process control, smart transmitters, and other systems where high‑resolution measurement, small size, and low power are critical. The ADS1110 communicates via a standard I²C interface with eight selectable addresses, making it easy to integrate into multi‑device designs.
