Overview
The LM2901DTBR2 is a low-power quad voltage comparator manufactured by onsemi, housed in a TSSOP-14 surface-mount package. It operates from a single supply of 3.0 V to 36 V or split supplies of ±1.5 V to ±18 V. The device features a typical input bias current of 25 nA and an input offset voltage of ±7.0 mV at +25°C. Electrical characteristics include a response time of 1.3 µs and an output saturation voltage of 130 mV at 4.0 mA sink current. It supports open-collector outputs compatible with TTL and CMOS logic families.
Feature Summary
- Supports single and split power supply configurations for flexible system integration
- Features low input bias current and low input offset voltage for precision sensing
- Includes ESD protection clamps on inputs to enhance operational reliability
- Outputs are compatible with standard TTL and CMOS logic families
Applications
- Level detection circuits
- Low-level signal sensing
- Memory interface applications
Procurement Notes
Verify the specific suffix DTBR2 corresponds to the TSSOP-14 tape and reel packaging configuration. Confirm that the ordering code matches the required temperature range and RoHS compliance status. Ensure the component source aligns with the manufacturer's official distribution channels to guarantee authenticity and traceability.
Selection Notes
Select this component when a quad comparator with low power consumption and wide supply voltage range is required. The TSSOP-14 package is suitable for space-constrained surface-mount designs. Consider the open-collector output structure for interfacing with various logic levels without additional level shifting components.
Part Context
This part belongs to the LM2901 family of single-supply quad comparators produced by onsemi. It shares architectural similarities with the LM339 and MC3302 but offers specific performance characteristics tailored for consumer, automotive, and industrial electronic applications requiring reliable analog-to-digital conversion.
Replacement Considerations

FAQ
What is the input common mode voltage range?
The input common mode voltage range extends down to ground (0 V) and up to the positive supply rail minus 1.5 V.
Can the differential input voltage exceed the supply voltage?
Yes, differential input voltages may be larger than the supply voltages without damaging the comparator inputs, provided they remain within the absolute maximum ratings.
