BA10339

Overview

The BA10339 is a quad general-purpose analog comparator manufactured by ROHM Semiconductor. It integrates four independent high-gain voltage comparators within a silicon monolithic integrated circuit structure. The device supports single supply operation from +3.0V to +36.0V and split supply operation from ±1.5V to ±18.0V. It features an open-collector output configuration, ground-sense input and output capabilities, and operates across a temperature range of -40°C to +85°C.

Feature Summary

• Operates with a wide operating supply voltage range
• Features standard pin assignments for compatibility
• Supports ground sense operation for both inputs and outputs
• Includes open collector output configuration

Applications

• General use
• Current monitor
• Battery monitor
• Multi vibrator

Procurement Notes

Verify the specific package variant (SOP14 or SSOP-B14) required for the design. Confirm RoHS compliance status through official datasheets. Check current availability as some variants may be discontinued or restricted in certain regions. Ensure ordering suffixes match the desired packaging format.

Selection Notes

Select this component when a quad comparator configuration is needed with low power consumption. It is suitable for applications requiring ground-referenced signals and wide voltage tolerance. Consider thermal dissipation limits if operating at high ambient temperatures or with significant load currents.

Part Context

The BA10339 belongs to the BA10339 Series, which includes variants like BA10339F and BA10339FV. These are part of a broader family of ground sense comparators that also includes the BA8391G, BA10393F, and BA2903/BA2901 series. The series shares common architectural features such as PNP input stages and open-collector outputs.

Replacement Considerations

BA10393F is a dual-channel alternative within the same series. BA2903xx and BA2901xx series offer similar functionality with different temperature ratings and offset voltage specifications.
