ADS1112

SBAS282D − JUNE 2003 − REVISED MARCH 2004

16-Bit Analog-to-Digital Converter with

Input Multiplexer and Onboard Reference

FEATURES

DESCRIPTION

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.

16 BITS, NO MISSING CODES

INL: 0.01% of FSR max

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.
