UPC271 pinout datasheet


C271C is High Performance Comparator. A high-performance comparator is an electronic component used to compare two voltage inputs and provide a digital output based on the comparison result. It is designed to offer precise and accurate voltage comparison with high-speed response and low input/output voltage offset.

The uPC271, uPC311 are voltage comparators that have input currents more than a hundred times lower than device like conventional standard type of 710. It is also designed to operate over a wide range of supply voltage.

High-performance comparators find applications in various fields, including analog-to-digital converters (ADCs), instrumentation, precision measurement systems, motor control, audio processing, and other circuits where accurate voltage comparison is essential.
