DESCRIPTIONThe ADS1112 is a precision, continuously self-calibrating
Analog-to-Digital (A/D) converter with two differential or three
single-ended channels and up to 16 bits of resolution in the
small MSOP-10 and leadless QFN-style (small-outline,
no-lead) packages. The onboard 2.048V reference provides
an input range of ±2.048V differentially. The ADS1112 uses
an I2 C-compatible serial interface and has two address pins
that allow a user to select one of the eight I2 C Slave
addresses. The ADS1112 operates from a single power
supply ranging from 2.7V to 5.5V.
The ADS1112 can perform conversions at rates of 15, 30, 60,
or 240 samples per second (SPS). The onboard
programmable gain amplifier (PGA), which offers gains of up
to eight, allows smaller signals to be measured with high
resolution. In single-conversion mode, the ADS1112
automatically powers down after a conversion, greatly
reducing current consumption during idle periods.
The ADS1112 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.
