LM393 Description

Short technical summary and product information.

The LM393 is a dual differential comparator IC manufactured by STMicroelectronics. It is designed for a wide range of applications requiring precise voltage comparison.

This comparator features two independent channels, each with an open-collector/open-drain output. It operates over a broad supply voltage range from 2V to 36V, making it versatile for various power supply designs. The typical propagation delay is 1.3 µs, ensuring reasonably fast response times in control circuits.

With an operating temperature range of 0°C to 70°C, the LM393 is suitable for commercial-grade applications. Key electrical characteristics include a low quiescent current per channel of 0.225 mA typical and a maximum offset voltage of 5 mV at 25°C. The input bias current is a maximum of 50 nA.

The LM393 is available in multiple package types including SOP, VSSOP, SOIC, TSSOP, and PDIP, supporting various board space and assembly requirements. Its output is compatible with TTL, MOS, and CMOS logic levels.
