APPLICATIONS

DESCRIPTION

The 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

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.
