Overview
The BA2901FV-E2 is a quad standard open-collector comparator manufactured by ROHM Semiconductor. It operates on a single power supply ranging from +2.0 V to +36.0 V, or dual supplies of ±1.0 V to ±18.0 V. The device features four independent channels within an SSOP-B14 package. Key electrical specifications include a typical response time of 1.3 µs, a maximum input offset voltage of 7 mV, and a typical input bias current of 50 nA. It supports an operating temperature range from -40°C to +125°C and includes built-in electrostatic protection circuits.
Feature Summary
- Supports wide power supply voltage ranges for flexible single or dual supply configurations.
- Enables ground-sense operation with inputs and outputs capable of functioning near the GND level.
- Incorporates internal electrostatic protection circuits to enhance component durability.
Applications
- General-purpose analog signal comparison
- Voltage monitoring circuits
- Threshold detection systems
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance with current environmental standards and pinout definitions. Confirm that the SSOP-B14 package dimensions align with the target PCB footprint requirements. Ensure that the design accounts for the open-collector output configuration, which requires appropriate external pull-up components for proper logic level translation.
Selection Notes
Select this component when a quad comparator with low input bias current and wide supply voltage tolerance is required. The open-collector output architecture allows for wired-OR connections and compatibility with various logic families through external pull-up selection. Consider the thermal performance within the specified temperature range during high-density board layouts.
Part Context
This part belongs to the BA2901 series of general-purpose comparators produced by ROHM Semiconductor. It is designed as a cost-effective solution for applications requiring multiple comparison functions in a compact surface-mount package. The series is characterized by its ability to operate close to ground potential, making it suitable for low-voltage sensing applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-compatibility with other quad comparators based on pinout and electrical parameter matching before substitution.
