12 Bit ADC (AD 7109) module is a single channel, high performance, low power integrating ADC. This module accepts true differential inputs, in the range of ±5V DC. Conversion rate is 30 conversions / second. An on board 3.58 MHz crystal clock is provided to drive the ICL 7109. . All inputs fully protected against static discharge, useful in the design of analytical instruments, process instruments and or using low speed transducers. The module utilizes Intersil’s ICL 7109, a 12-bit binary A to D converter for microprocessor interface. The ICL 7109 is a high performance, low power integrating, microprocessor compatible A to D converters. The module is designed to interface with all the microprocessor trainers. The module needs an external supply of +5V @ 500mA, and a -5V @ 300mA to power up the system.

Specifications:

• 12 BIT analog to digital converter.
