BA10339FV-E2

Overview

The BA10339FV-E2 is a quad analog comparator manufactured by ROHM Semiconductor, housed in an SSOP-B14 surface-mount package. It operates on a single supply voltage ranging from 3 V to 36 V or dual supplies of ±1.5 V to ±18 V. The device features four independent channels with open-collector outputs capable of sourcing up to 16 mA. Key electrical specifications include a typical response time of 1.3 µs, a maximum input offset voltage of 5 mV, and a typical input bias current of 50 nA. The quiescent current per channel is typically 0.8 mA, and the unit supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Quad-channel architecture providing four independent comparison functions within a single integrated circuit.
• Wide single-supply operation capability spanning from 3 V to 36 V for flexible power integration.
• Open-collector output structure allowing direct interfacing with various logic families and load types.
• Standard pinout compatibility facilitating straightforward replacement in existing general-purpose designs.

Applications

• General-purpose signal comparison circuits
• Voltage level detection systems
• Simple threshold monitoring applications

Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing lots. Validate package integrity upon receipt as the SSOP-B14 form factor requires careful handling during assembly processes.

Selection Notes

Select this component when a quad comparator configuration is required within a compact surface-mount footprint. Ensure design requirements align with the 1.3 µs response time and 16 mA output drive capability. Verify that the 3 V minimum supply voltage meets system power constraints before finalizing the bill of materials.

Part Context

This part belongs to the BA10339 series of standard open-collector comparators produced by ROHM Semiconductor. It serves as the SSOP-B14 packaged variant of the broader family, which also includes DIP and SOP configurations. The series is designed for cost-effective general-purpose comparison tasks requiring multiple channels.

Replacement Considerations

Publicly confirmed substitute part numbers include LM2901F-E2 and LM339FV-E2 from Rohm Semiconductor. These alternatives offer similar functional characteristics but require verification of pinout compatibility and electrical parameter alignment prior to implementation.
