The Texas Instruments TLC372CPW is a dual LinCMOS differential comparator. It is fabricated using Texas Instruments' LinCMOS technology, which is a proprietary process that combines the low power consumption of CMOS with the high speed and noise immunity of bipolar devices. The TLC372CPW is designed to operate from a single power supply, but can also be operated from dual supplies. It has an extremely high input impedance, which allows it to be directly interfaced with high-impedance sources. The outputs are n-channel open-drain configurations, which can be connected to achieve positive-logic wired-AND relationships.

The TLC372CPW is ideal for a wide range of applications, including:

• Window comparators
• Zero-crossing detectors
• Level detectors
• Phase comparators
• Pulse-width modulators
• Schmitt triggers
• Voltage-to-frequency converters
• Analog-to-digital converters

The TLC372CPW is available in an 8-pin TSSOP package. It is characterized for operation from 0°C to 70°C.
