Frequently Asked Questions
What is the LMV339IDR used for?
The LMV339IDR is a quad low-voltage comparator designed for battery-powered and portable applications. It is used in threshold detection circuits, window comparators, level translators, motor control, and power-supply monitoring where low supply voltage (1.8V–5.5V) and ultra-low quiescent current are required.
What supply voltage does the LMV339IDR support?
The LMV339IDR operates on a single supply from 1.8V to 5.5V, making it compatible with 1.8V, 2.5V, 3.3V, and 5V digital systems. It can also be operated with a split supply as long as the differential does not exceed 5.5V.
What is the output structure of the LMV339IDR?
The LMV339IDR has open-drain outputs, which means each comparator output is a transistor whose collector is left unconnected internally. This allows the outputs to be pulled up to voltages different from the supply, enabling easy interfacing with different logic families and wired-AND configurations.
What are good alternatives to the LMV339IDR?
Drop-in or functionally similar alternatives include the LM339 (5V, bipolar, classic quad comparator), LMV393 (dual low-voltage version by TI), MCP6544 (Microchip quad comparator, 1.8V–5.5V), and TSVM339 (SOIC-14, pin-compatible). Always verify supply voltage range, offset specs, and output type before substituting.
How does the LMV339IDR differ from the LM339?
The LMV339IDR is the low-voltage evolution of the classic LM339. While the LM339 requires 3V–32V and draws higher quiescent current, the LMV339IDR operates from 1.8V to 5.5V with only ~12µA per comparator, making it far more suitable for 3.3V and 1.8V digital systems and battery-powered products.
