Frequently Asked Questions
What is the supply voltage range of the LM2901D?
The LM2901D operates over a wide supply voltage range of 3V to 28V on a single supply, or ±1.5V to ±14V on a dual supply. This flexibility makes it suitable for a broad range of analog and digital system designs including 3.3V, 5V, 12V, and 24V applications.
What output type does the LM2901D use and how should it be connected?
The LM2901D features open-collector (open-drain) outputs, which require an external pull-up resistor connected to the desired logic supply voltage. This allows the outputs to interface with different logic families and supports wired-AND configurations where multiple comparator outputs share a common pull-up.
What are typical applications for the LM2901D quad comparator?
The LM2901D is commonly used in voltage threshold detection, window comparators, oscillators, pulse generators, and zero-crossing detectors. It is also used in motor drive circuits, power supply supervisors, and industrial control systems where multiple analog signal comparisons are needed simultaneously.
What package does the LM2901D come in and what are its dimensions?
The LM2901D is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) package, also identified by JESD-30 code R-PDSO-G14. This surface-mount package is compact and suitable for automated PCB assembly, making it ideal for space-constrained designs.
How does the LM2901D compare to the LM339 comparator?
The LM2901D and LM339 are functionally similar quad comparators with open-collector outputs, but the LM2901D is optimized for single-supply operation starting from 3V, making it more suitable for low-voltage systems. Both devices offer 4 channels, but the LM2901D in SOIC-14 provides a smaller PCB footprint compared to DIP-14 variants of the LM339.
