16-Bit ANALOG-TO-DIGITAL CONVERTER
with Onboard Reference
FEATURES DESCRIPTION
COMPLETE DATA ACQUISITION SYSTEM IN The ADS1110 is a precision, continuously self−calibrating A 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. The
ONBOARD REFERENCE:

serial interface and operates from a single power supply
ONBOARD PGA ranging from 2.7V to 5.5V. ONBOARD OSCILLATOR The ADS1110 can perform conversions at rates of 15, 30, 60,
or 240 samples per second. The onboard programmable
