ICL7107CPL+ Product Overview

The ICL7107CPL+ is a high-performance, low-power, 3.5 digit analog-to-digital converter (ADC) designed by Maxim Integrated. This integrated circuit is specifically engineered to provide a direct digital readout of analog signals, making it an ideal choice for a wide range of applications that require precise digital displays of analog values, such as multimeters, digital panel meters, and temperature displays.

Key Features

• High Integration: The ICL7107CPL+ integrates a seven segment decoder, display drivers, a reference, and a clock all into a single chip, simplifying design and reducing component count.
• Resolution: The device offers a 3.5 digit resolution, which is capable of displaying readings from 0 to ±1999, allowing for accurate representation of the measured signal.
• Low Power Consumption: Designed with power efficiency in mind, the ICL7107CPL+ is suitable for battery-operated applications due to its low power requirements.
• Auto-Zeroing Feature: The chip automatically corrects for any offset, ensuring that the zero reading is always accurate without manual adjustment.
• True Differential Input: The ICL7107CPL+ is capable of measuring the difference between two input signal levels, which is essential for rejecting common mode noise and improving measurement accuracy.
• Overrange and Underrange Signals: It includes signals that can be used for annunciators to indicate when the input is out of range.
• Polarity Indication: The device can automatically detect and display the polarity of the input signal, ensuring that users are aware of the signal's direction.
