Overview
The LM339AMX is a quad differential comparator manufactured by Texas Instruments, housed in a 14-SOIC surface-mount package. It operates on a single or dual power supply ranging from 2V to 36V (±1V to ±18V). Key electrical specifications include a maximum input offset voltage of 2mV at 5V, an input bias current of 0.25µA at 5V, and a typical output current of 18mA at 5V. The device features open-collector outputs and has a static current consumption of up to 2.5mA. It is designed for operation within a temperature range of 0°C to 70°C.
Feature Summary
- Integrates four independent differential comparators in a compact surface-mount package
- Supports wide single-supply or split-rail voltage operation
- Features low input bias current and low input offset voltage characteristics
- Provides open-collector outputs suitable for wired-AND logic configurations
Applications
- Precision threshold detection circuits
- Voltage monitoring systems
- On-off control applications
Procurement Notes
Verify the specific revision level and manufacturing date code upon receipt, as component variants may exist. Confirm that the received units match the 14-SOIC package dimensions and pinout configuration specified in the official datasheet. Ensure compliance with RoHS3 standards if required by the end application. Check for any product change notices related to this part number before finalizing procurement plans.
Selection Notes
Select this component when a quad comparator with low offset voltage is required in a surface-mount format. The open-collector output allows flexibility in interfacing with various logic families through external pull-up resistors. Consider the 2V minimum supply voltage for low-power battery applications. Verify thermal dissipation requirements for the SOIC-14 package under maximum load conditions.
Part Context
This part belongs to the LM339 family of analog comparators, which are widely used for general-purpose comparison tasks. The 'MX' suffix indicates the tape-and-reel packaging variant of the standard LM339M. It shares functional compatibility with other members of the series but differs in packaging and potentially in specific performance tolerances defined by the manufacturer's quality grades.
Replacement Considerations
LM339AMX/NOPB is listed as a direct replacement option.
