BA10393F-E2

Overview

The BA10393F-E2 is a dual-channel general-purpose comparator manufactured by Rohm Semiconductor. It operates on a single supply voltage ranging from 2V to 36V or dual supplies of ±1V to ±18V. The device features an open-collector output capable of sinking up to 16mA at 5V. Key electrical parameters include a maximum input offset voltage of 5mV, a typical response time of 1.3µs, and a quiescent current of approximately 400µA. It is housed in an 8-pin SOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports ground-sensed input and output operation, allowing signals near the ground potential to be processed effectively within single-supply configurations.
• Features wide operating supply voltage compatibility, enabling use across diverse power systems from low-voltage battery applications to higher voltage industrial circuits.
• Provides open-collector outputs that facilitate direct interfacing with various logic families and allow for wired-OR connection capabilities.

Applications

• Temperature sensing circuits utilizing thermistors or thermal sensors
• Pressure monitoring systems with analog sensor interfaces
• Current detection and protection circuits

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and lead times directly with suppliers. Ensure the specific suffix matches the required packaging format. Check for any obsolescence notices or recommended new designations before finalizing procurement plans.

Selection Notes

Select this component when dual comparators are needed with wide voltage tolerance and ground-referenced signal handling. Consider the open-collector output requirement for pull-up resistor integration. Evaluate the 1.3µs response time against system speed requirements. Verify SOP-8 footprint compatibility during PCB layout phase.

Part Context

This part belongs to Rohm's standard comparator family, sharing functional similarities with industry-standard devices like the LM393. It offers comparable performance metrics including dual-channel architecture and low power consumption. The device serves as a versatile solution for basic voltage threshold detection and waveform shaping tasks in consumer and industrial electronics.

Replacement Considerations

LM393FJ-E2 is listed as a similar replacement option by the same manufacturer. Other potential substitutes include STMicroelectronics' LM193DT and LM293DT series components. Verify pinout compatibility and electrical parameter margins before substituting.
