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, 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 consump-
tion are major considerations. Typical applications include
portable instrumentation, industrial process control and smart
transmitters.
