Overview
The BA10339F-E2 is a quad analog comparator manufactured by Rohm Semiconductor, housed in a 14-SOP surface-mount package. It features four independent channels with open-collector outputs capable of sourcing 16mA at 5V. The device operates on a single supply voltage ranging from 3V to 36V or dual supplies from ±1.5V to ±18V. Key electrical parameters include a maximum input offset voltage of 5mV, typical input bias current of 50nA, and a response time of 1.3µs. It functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Quad-channel architecture providing four independent high-gain comparators in a single integrated circuit.
- Open-collector output configuration allows flexible interfacing with various logic families and voltage levels.
- Wide single-supply operation capability spanning from 3V to 36V for diverse power design requirements.
- Ground-sense input and output functionality enabling signal processing near the ground potential.
Applications
- General-purpose analog signal comparison circuits
- Voltage level detection systems
- Threshold monitoring applications
Procurement Notes
Verify component authenticity through official Rohm Semiconductor channels or authorized distributors. Confirm the specific suffix E2 indicates RoHS compliance and lead-free status as per the datasheet. Ensure the 14-SOP package variant matches the target PCB footprint. Check for any product change notices or end-of-life announcements prior to finalizing procurement plans.
Selection Notes
Select this component when a quad comparator solution is required with wide supply voltage flexibility. The open-collector output necessitates external pull-up resistors for proper logic high generation. Consider the 1.3µs response time for speed-sensitive designs. Verify that the 5mV max input offset voltage meets the precision requirements of the specific application environment.
Part Context
The BA10339 series represents Rohm's standard general-purpose analog comparators. The BA10339F-E2 specifically denotes the quad channel version in SOP-14 packaging. This series is designed for cost-effective solutions in consumer electronics and industrial control where multiple comparison functions are needed without occupying excessive board space.
Replacement Considerations
The LM2901F-E2 is listed as a manufacturer-recommended substitute. Other similar alternatives include the LM339FV-E2. Verify pin compatibility and electrical parameter alignment before substitution.
