Overview
The LM393F-GE2 is a dual-channel analog comparator manufactured by ROHM Semiconductor, designed for general-purpose applications. It operates within a supply voltage range of 3 V to 32 V and features an open collector output type capable of sourcing up to 16 mA per channel. The device exhibits a typical response time of 1 µs and consumes 600 µA of operating current. Key electrical parameters include a maximum input offset voltage of 4.5 mV and an input bias current of 250 nA. It supports surface mount installation in an SOP-8 package and functions reliably across a temperature range of -40 °C to +85 °C.
Feature Summary
- Ground-sensed input and output capability allows operation with common-mode voltage including ground level.
- Open collector output structure enables direct interfacing with various logic families such as TTL and CMOS.
- Low input offset voltage ensures high precision in differential voltage comparison tasks.
Applications
- General purpose voltage monitoring circuits
- Threshold detection systems
- Analog-to-digital conversion interfaces
Procurement Notes
Verify the specific suffix GE2 against official ROHM documentation to confirm RoHS compliance and packaging details. Confirm that the SOP-8 pinout matches the target PCB footprint design. Ensure the component status is reviewed, as similar variants may carry different lifecycle statuses affecting long-term availability.
Selection Notes
Select this component when a dual-channel comparator with ground-referenced inputs is required for single-supply operations. The open collector output necessitates external pull-up resistors for proper high-state logic levels. Consider the 1 µs response time and 4.5 mV offset voltage limits against application speed and accuracy requirements before finalizing the design.
Part Context
This part belongs to the LM393F series of dual independent precision voltage comparators. It shares functional similarities with other industry-standard comparators but is distinguished by its specific manufacturing specifications from ROHM Semiconductor. The device is categorized under analog comparators within the amplifier ICs subcategory.
Replacement Considerations
Direct substitutes include LM393FV-E2 (SSOP-8) and LM393FJ (SOP-J8). Verify pin compatibility and package dimensions before substitution. Note that these alternatives may have different thermal or mechanical characteristics despite identical electrical performance.
