Overview
The BA2901F-E2 is a quad analog comparator manufactured by ROHM Semiconductor, housed in a 14-SOP surface-mount package. It operates on a single supply voltage ranging from 2V to 36V or dual supplies of ±1V to ±18V. The device features four independent channels with open-collector outputs capable of sourcing up to 16mA per channel. Key electrical specifications include a typical response time of 1.3µs, a maximum input offset voltage of 7mV, and a typical input bias current of 50nA. It functions within an extended temperature range of -40°C to +105°C.
Feature Summary
- Supports wide operating supply voltage ranges for flexible power design
- Features standard comparator terminal connections for easy integration
- Allows input and output signals to operate near ground potential
- Includes built-in electrostatic protection circuits
Applications
- General-purpose signal comparison circuits
- Voltage monitoring systems
- Threshold detection applications
Procurement Notes
Verify component authenticity through authorized distributors as the part may be subject to end-of-life status. Confirm RoHS compliance details and specific packaging options such as tape and reel quantities before ordering. Ensure the selected variant matches the required SOP-14 footprint and lead configuration for PCB compatibility.
Selection Notes
Select this component when a quad comparator with low power consumption and wide voltage tolerance is required. Consider the open-collector output type for necessary pull-up resistor implementation. Evaluate the 1.3µs response time against system speed requirements and ensure the 14-SOP package fits the available board space constraints.
Part Context
This device belongs to the BA2901xx series of general-purpose analog comparators. It shares architectural similarities with other ROHM comparator families but is distinct in its quad-channel configuration and specific electrical characteristics. The part is designed for cost-effective solutions in consumer and industrial electronics requiring multiple comparison functions.
Replacement Considerations
Direct substitutes include the LM2901F-E2, which offers similar quad-channel functionality with slight variations in offset voltage and supply range. Verify pinout compatibility and thermal performance when transitioning between these comparable ROHM products.
