ADS1112  
SBAS282D − JUNE 2003 − REVISED MARCH 2004  
16-Bit Analog-to-Digital Converter with  
Input Multiplexer and Onboard Reference  
FEATURES  
DESCRIPTION  
D
COMPLETE DATA ACQUISITION SYSTEM IN  
THE MSOP-10 AND LEADLESS QFN-STYLE  
PACKAGES  
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  
an I2C-compatible serial interface and has two address pins  
that allow a user to select one of the eight I2C Slave  
addresses. The ADS1112 operates from a single power  
supply ranging from 2.7V to 5.5V.

ONBOARD REFERENCE:  
Accuracy: 2.048V 0.05%  
Drift: 5ppm/°C  
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.
