Overview
The LM2901F-E2 is a quad analog comparator manufactured by ROHM Semiconductor, housed in a SOP-14 surface-mount package. It features four independent channels with open-collector outputs and operates within a supply voltage range of 3 V to 32 V. The device draws a typical operating current of 1.2 mA per channel and provides an output current capability of 16 mA. Key electrical specifications include a maximum input offset voltage of 4.5 mV, an input bias current of 250 nA, and a response time of 1 µs. It supports a wide operating temperature range from -40 °C to +125 °C.
Feature Summary
- Ground-sense input and output architecture allowing operation near the negative rail
- Open-collector output configuration for flexible interfacing
- Low power consumption suitable for battery-operated applications
Applications
- General purpose signal comparison circuits
- Voltage monitoring systems
- Threshold detection applications
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the SOP-14 package dimensions match the target PCB footprint. Confirm that the 1 µs response time meets system timing requirements under the intended load conditions.
Selection Notes
Select this component when a quad comparator with ground-referenced inputs is required. The low offset voltage of 4.5 mV ensures accuracy in precision threshold applications. The wide supply voltage range accommodates various single-supply configurations without level shifting.
Part Context
This part belongs to the LM2901 series of ground-sense comparators. It serves as a standard-grade general-purpose solution distinct from automotive-specific variants like the LM2901EYFV-CE2. The SOP-14 package offers a compact form factor compared to through-hole alternatives.
Replacement Considerations
The LM2901F is listed as an alias for this part number. Verify functional equivalence before substituting with other quad comparators, as input offset voltage and response times may vary significantly across different manufacturers.
