Overview
The LMV339IPWR is a dual low-voltage analog comparator manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device features an open-drain output configuration and offers a typical response time of 200 ns. Key electrical specifications include a maximum input offset voltage of 7 mV, an operating supply current of 210 µA, and an input bias current of 250 nA. It is housed in an 8-pin TSSOP package and supports a wide operating temperature range from -40°C to +125°C.
Feature Summary
- Dual-channel differential comparison capability within a compact surface-mount package
- Low power consumption suitable for battery-operated applications
- Wide single-supply voltage operation range
- Open-drain outputs allow flexible interfacing with various logic families
Applications
- Battery-powered monitoring systems
- Threshold detection circuits
- Low-voltage signal processing
- Temperature sensing interfaces
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the TSSOP-8 footprint matches the target PCB design. Ensure the voltage supply rails remain within the 2.7 V to 5.5 V operational limits to maintain specified performance characteristics. Check for RoHS compliance documentation if required by assembly standards.
Selection Notes
Select this component when a dual comparator is required with low quiescent current and operation below 5.5 V. It serves as a low-voltage alternative to standard comparators. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate the 7 mV offset voltage against application sensitivity needs.
Part Context
This part belongs to the LMV393/LMV339 family of low-voltage comparators from Texas Instruments. It provides a dual-channel solution compared to quad-channel variants like the LM339 series. The device is designed for modern low-power electronics requiring precise threshold detection without high supply voltages.
Replacement Considerations
LMV393IPWR: Single-channel version of the same family. LMV339DR: Quad-channel variant with similar electrical characteristics but different pin count.
