ICL7116CPL ,Digital Voltmeter IC - DIP Package, LCD Direct Drive, for Accurate Voltage Measurements

The ICL7116CPL is a high-performance 3(1/2) digit analog-to-digital converter designed for use with liquid crystal displays (LCDs). It utilizes a dual-slope conversion technique that automatically rejects noise and interference, making it suitable for applications requiring precise and stable measurements, such as digital panel meters. This IC features a unique display hold function, allowing indefinite display of the current reading.

With high input impedance differential inputs and low noise design, the ICL7116CPL provides reliable performance for measuring voltage, resistance, temperature, and other analog parameters. It operates over a temperature range of 0C to +70C and is housed in a 40-lead plastic DIP package for easy through-hole mounting. The IC also includes features like zero reading, low power consumption, and clock and reference on-chip for improved integration in design applications.
