LM293H Description

Short technical summary and product information.

The Thomson-CSF LM293H is a dual comparator designed for precision voltage comparison applications. It features two independent channels with open-collector outputs, compatible with TTL, DTL, ECL, MOS, and CMOS logic systems.

Key electrical characteristics include a wide supply voltage range from 2V to 36V for single or dual supplies (±1.0V to ±18V). The device exhibits very low supply current drain, independent of supply voltage, making it suitable for battery-operated applications. It boasts a low input bias current of 25 nA and a low input offset current of ±5 nA, with a maximum offset voltage of ±3 mV.

The LM293H has a propagation delay time of 0.7 µs and a low output saturation voltage of 250 mV at 4 mA. The input common-mode voltage range includes ground, and the differential input voltage range is equal to the power supply voltage. It operates reliably within a temperature range of -25°C to 85°C.

This comparator is available in an 8-Bump (12 mil) DSBGA package. Its design advantages include high precision, reduced offset voltage drift over temperature, and the ability to sense near ground, eliminating the need for dual supplies in many applications.
