DESCRIPTION

The ADS1000 is an I2C-compatible serial interface Analog-to-Digital (A/D) converter with differential inputs and 12 bits of resolution in a tiny SOT23-6 package. Conversions are performed ratiometrically, using the power supply as the reference voltage. The ADS1000 operates from a single power supply ranging from 2.7V to 5.5V.
