LM393AD Description

Short technical summary and product information.

The LM393AD is a dual voltage comparator IC manufactured by STMicroelectronics. It is designed for applications requiring precise voltage level detection. This component features a wide single supply voltage range from 2V to 36V, or dual supplies from ±1V to ±18V. Its very low supply current is independent of the supply voltage, consuming only 0.4mA. The input common-mode voltage range includes ground, making it versatile for various circuit designs.

The LM393AD offers a low input bias current of 25nA typical and a low input offset current of ±5nA typical. The input offset voltage is typically ±1mV. It provides a low output saturation voltage of 250mV typical at 4mA. The differential input voltage range is equal to the supply voltage. Outputs are compatible with TTL, DTL, ECL, MOS, and CMOS logic levels.

This comparator is available in a surface-mount SOIC package, suitable for automated assembly processes. The operating temperature range for the LM393AD is 0°C to 70°C, with a maximum power dissipation of 830mW in an SOIC package. Its design makes it suitable for a wide array of electronic applications where reliable voltage comparison is needed.
