INTERSIL 3.5 Digit CMOS ADC, 40-Pin DIP

The INTERSIL 3.5 Digit CMOS ADC is a precision analogue-to-digital converter designed for accurate measurement applications. This integrated circuit features a 3.5-digit resolution, providing a clear and detailed readout for data acquisition systems. It operates with a sampling rate of 3 samples per second (3SPS), making it suitable for monitoring slowly changing signals or processes where high-speed conversion is not required.

The device utilises a differential input channel type, which helps to reject common-mode noise and improves measurement accuracy in electrically noisy environments. Data is output via a parallel interface, allowing for straightforward integration with microprocessors, microcontrollers, or digital display drivers.
