The ADS1100 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. Conversions are performed ratiometrically, using the power supply as the reference voltage. The ADS1100 uses an I2C-compatible serial interface and operates from a single power supply ranging from 2.7V to 5.5V.

The ADS1100 can perform conversions at rates of 8, 16, 32, or 128 samples per second. The onboard Programmable Gain Amplifier (PGA), which offers gains of up to 8, allows smaller signals to be measured with high resolution. In single-conversion mode, the ADS1100 automatically powers down after a conversion, greatly reducing current consumption during idle periods.

The ADS1100 is designed for applications requiring high-resolution measurement, where space and power consumption are major considerations. Typical applications include portable instrumentation, industrial process control and smart transmitters.
