LM293N Description

Short technical summary and product information.

The SIG LM293N is a dual voltage comparator designed for versatile applications requiring precise voltage comparisons. It operates from a wide single supply voltage range of +2V to +36V or dual supplies from ±1V to ±18V, making it suitable for diverse power environments.

This comparator exhibits a very low supply current of 0.4mA, independent of the supply voltage, contributing to power efficiency. Key electrical characteristics include a low input bias current of 25nA typical, a low input offset current of ±5nA typical, and a low input offset voltage of ±1mV typical. The input common-mode voltage range includes ground, even when operated from a single supply.

The LM293N offers TTL, DTL, ECL, MOS, and CMOS compatible outputs, ensuring broad integration with different logic families. Its output saturation voltage is typically 250mV at 4mA. The device is housed in a DIP-8 package and operates within a temperature range of -40°C to +105°C.

This component is ideal for applications requiring reliable voltage level detection and switching. Its robust design and wide operating parameters make it a suitable choice for various electronic circuits.
