Texas Instruments ADS1100 Datasheet
The ADS1100 is a precision, continuously self‑calibrating 16‑bit ADC offered in a tiny SOT‑23‑6 package. It features a programmable gain amplifier (gain = 1, 2, 4, or 8), low noise (4 µV p‑p), and a selectable data rate from 8 SPS to 128 SPS. Power is supplied from 2.7 V to 5.5 V and the device consumes only about 90 µA in active mode. Communication is via a standard I²C (2‑wire) interface, and eight factory‑programmed I²C addresses are available.
The converter is intended for portable instrumentation, industrial process control, smart transmitters, consumer goods, factory automation, and temperature measurement. It operates from –40 °C to +125 °C, provides differential inputs with typical input impedances of 2.4 MΩ/PGA (differential) and 8 MΩ (common‑mode), and includes continuous self‑calibration that cannot be disabled.
