DESCRIPTION

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 highresolution

measurement, where space and power consumption

are major considerations. Typical applications include

portable instrumentation, industrial process control, and smart

transmitters.
