ADS1100

Introduction

The ADS1100 is a precision, continuously self-calibrating Analog-to-Digital (A/D) converter with differential inputs and up to 16 bits of resolution in a small SOT23-6 package. Conversions are performed ratiometrically, using the power supply as the reference voltage. The ADS1100 uses an I2C-compatible serial interface and operates from a single power supply ranging from 2.7V to 5.5V.

Installation

• connect 5V to Vcc, 0V to GND i.e. in the Interrupts part of the board.
• connect SDA to pin nr 12 labelled TX, SCL to pin nr 16 I2C SCL (Port D.0) labelled RX in the UARTS part
