Frequently Asked Questions
What is the LMV342MA/NOPB and what does it do?
The LMV342MA/NOPB is a dual general-purpose voltage comparator from Texas Instruments housed in a SOT-23-5 package. It compares two analog input voltages and outputs a digital signal via an open-drain output, making it ideal for level detection, window comparators, and threshold monitoring in low-voltage systems operating from 2.7V to 5V.
What supply voltage does the LMV342MA/NOPB support?
The LMV342MA/NOPB operates on a single supply from 2.7V to 5V, or a dual supply of ±1.35V to ±2.5V. The rail-to-rail input range allows inputs to swing all the way to GND and VCC, making it suitable for battery-powered and 3.3V digital system applications.
What is the operating temperature range of the LMV342MA/NOPB?
The LMV342MA/NOPB is rated for an extended industrial temperature range of −40°C to +125°C, making it suitable for automotive, industrial, and outdoor equipment applications that experience wide temperature swings.
What are common alternatives to the LMV342MA/NOPB?
Pin-compatible and functionally equivalent alternatives include the LMV393 (dual comparator in SOT-23-8), MCP6542 (Microchip dual comparator, 1.8V–5.5V), and TLV1701 (TI single comparator with hysteresis). For drop-in SOT-23-5 replacements, consider LMV321 (single) or look for parts with equivalent open-drain outputs and rail-to-rail inputs.
Is the LMV342MA/NOPB RoHS compliant and lead-free?
Yes. The NOPB suffix explicitly denotes No Lead (Pb-Free), and the LMV342MA/NOPB fully complies with RoHS and WEEE directives. It carries MSL rating of 1, meaning unlimited floor life at standard conditions, simplifying SMT assembly.
