The ICL7107CPLZ is part of Intersil Corporation’s data acquisition, analog-to-digital conversion, and control integrated circuit product line. The ICL7107CPLZ is a 3.5 digit, low cost, CMOS Analog-to-Digital Converter (ADC) with a dual slope integrating A/D conversion technique. It is designed to provide very high accuracy and high resolution in a wide variety of data acquisition and process control applications.

The ICL7107CPLZ is used in a variety of data acquisition, control, and monitoring applications including industrial process control, medical instrumentation, and consumer electronics. It can be used to measure temperature, pressure, flow rates, current, and voltage in process control and scientific instrumentation. It can also be used to measure sound, light, and acceleration in consumer electronics.

The ICL7107CPLZ is a monolithic integrated circuit that integrates two digitally-controlled active low-pass filters, two voltage reference pins, a D/A converter, a sample and hold amplifier, an analog multiplexer, two 12-bit A/D converters, and a CPU interface. It features high frequency input arguments, low voltage supply current, and high reference voltage accuracy. It also features self calibration, digital calibration and digital output offset adjustment.

The ICL7107CPLZ works by using a dual slope integrating conversion technique. This means that it first converts the analog input signal into a digital format. The digital representation of the analog signal is then compared to a reference voltage and the differences are integrated over a given period of time. This integration process continues until the differences between the analog signal and the reference voltage reach a predetermined level, after which the output is a 12-bit binary word representing the analog input.

The ICL7107CPLZ is an ideal choice for any application that requires accurate and reliable measurement of analog signals over a wide range of frequencies and environmental conditions. Its features including self calibration, digital calibration and digital output offset adjustment ensure it provides highly accurate and reliable results every time. Its low voltage supply current ensures low power consumption, making it a great choice for many battery powered and ultra-low power applications.
