Overview of LM393ADR by Texas Instruments

The LM393ADR is a precision dual differential comparator that is particularly suitable for various industrial applications. This component is housed in an 8-SOIC package, making it compact and well-suited for space-constrained environments. The operational temperature range is from 0 to 70 degrees Celsius, which fits within the commercial temperature grade category. This ensures that the part can perform effectively in typical conditions without the risk of failure due to environmental temperature fluctuations.

Manufactured by Texas Instruments, the LM393ADR utilizes bipolar technology, characterized by its low average bias current of a maximum of 0.4 µA and an even lower bias current of 0.05 µA at 25°C. Its input offset voltage can reach a maximum of 2000 µV, a critical specification for applications that require precision signal processing. The output type of this comparator is open-collector or open-drain, facilitating the connection of multiple outputs and making it favorable for wired-AND configurations.

The part adheres to various environmental compliance standards, including Pb-free, RoHS, and REACH compliance, indicating its suitability for eco-friendly applications. Its current life cycle is marked as active, ensuring its availability for procurement moving forward. With a long history of introduction dating back to April 1988, it has been a reliable choice in the market for over three decades.
