STMicroelectronics Quad Precision Voltage Comparator, 1.3µs, SOIC-14

The STMicroelectronics Quad Precision Voltage Comparator is a high-performance integrated circuit designed for demanding analogue signal processing applications. This IC features four independent precision comparators in a single compact SOIC-14 package, offering excellent space efficiency for complex circuit designs.

Engineered for versatility, the comparator operates across a wide supply voltage range from 2V to 36V, making it suitable for both low-power and industrial-level systems. Its fast 1.3 microsecond (µs) response time ensures quick and accurate detection of voltage threshold crossings, which is critical for timing circuits, zero-crossing detectors, and waveform shaping.

The device utilises an open-collector output type, providing flexible interfacing options by allowing the output to be pulled up to a voltage different from the chip's supply. This is ideal for level shifting and driving loads such as LEDs, relays, or other logic families. With an operational temperature range of 0°C to 70°C, it is reliably suited for commercial-grade electronic equipment, from power management modules to sensor interfaces and analogue-to-digital converter (ADC) window circuits.

Housed in a robust SOIC (Small Outline Integrated Circuit) package, it is designed for easy surface-mount assembly (SMT). Its precise voltage comparison capability makes it a fundamental component for creating voltage monitors, oscillators, and pulse generators, ensuring stable and accurate performance in a vast array of electronic projects and professional designs.
