ADS1100
SBAS239B – MAY 2002 – REVISED NOVEMBER 2003
Self-Calibrating, 16-Bit ANALOG-TO-DIGITAL CONVERTER
FEATURES DESCRIPTION COMPLETE DATA ACQUISITION SYSTEM IN A The ADS1100 is a precision, continuously self-calibrating TINY SOT23-6 PACKAGE Analog-to-Digital (A/D) converter with differential inputs and up to 16 bits of resolution in a small SOT23-6 package.
16-BITS NO MISSING CODES
Conversions are performed ratiometrically, using the power
INL: 0.0125% of FSR MAX
supply as the reference voltage. The ADS1100 uses an CONTINUOUS SELF-CALIBRATION I2C-compatible serial interface and operates from a single power supply ranging from 2.7V to 5.5V.
SINGLE-CYCLE CONVERSION
The ADS1100 can perform conversions at rates of 8, 16, 32,
