Overview
The LM339AMX/NOPB is a quad differential analog comparator manufactured by Texas Instruments. It features low power consumption and low offset voltage characteristics, making it suitable for precision applications. The device operates within a supply voltage range of 2 V to 36 V or ±1 V to ±18 V. It utilizes an SOIC-14 narrow surface-mount package. Key electrical parameters include a maximum input offset voltage of 5 mV, an input bias current of 250 nA, and a response time of 1.3 µs. Each channel provides an output current capability of 6 mA.
Feature Summary
- Integrates four independent differential comparators in a single package
- Operates with low power consumption and low offset voltage
- Features open-collector outputs compatible with various logic families
Applications
- Temperature sensing circuits
- Supervisory control systems
- Level detection applications
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free construction compliant with RoHS standards. Confirm the 'M' designation corresponds to the SOIC-14 narrow package variant. Ensure the 'A' grade specification aligns with required offset voltage tolerances for the target design. Cross-reference the datasheet revision date to confirm parameter validity against current manufacturing specifications.
Selection Notes
Select this component when a quad comparator configuration is required in a compact surface-mount form factor. The low offset voltage specification supports applications demanding high accuracy in signal comparison. Verify that the open-collector output architecture matches the pull-up requirements of the downstream circuitry. Consider the operating temperature range and supply voltage limits relative to the system environment.
Part Context
This part belongs to the LM339 family of quad comparators from Texas Instruments. It shares functional similarities with other variants such as the LM339N and LM339DR but differs in package type and manufacturing compliance. The NOPB suffix denotes non-pb (lead-free) status, distinguishing it from older tin-lead versions. It serves as a direct replacement for standard LM339 devices requiring surface-mount assembly.
Replacement Considerations
