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
2
I
C-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 consump-
tion 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.

    ... V Figure 7 covers only half the ADS1100 input scale because it does not produce differentially negative inputs; therefore, one bit of resolution is lost.
