Overview
The LM339A-TR is a quad independent voltage comparator manufactured by 3PEAK, housed in a TSSOP14 package. It operates on a wide single supply of +2.5 V to +36 V or dual supplies of ±1.25 V to ±18 V. Key electrical specifications include a quiescent current of 150 μA per channel, a maximum input bias current of 1 nA at 25°C, and a maximum offset voltage of ±6.0 mV. The device supports an operating temperature range from −40°C to 125°C and features open-collector outputs capable of wired-AND configurations.
Feature Summary
- Features low power consumption with supply current independent of the supply voltage, making it suitable for battery operation.
- Supports direct interfacing with TTL and CMOS logic families due to compatible output structures.
- Includes internal differential input voltage range equal to the supply voltage and common-mode input range that includes ground.
Applications
- High-speed line or digital line receivers
- Peak and zero-crossing detectors
- Threshold detectors and discriminators
- Sensing applications at ground or supply lines
Procurement Notes
Verify the specific package type matches the design requirements, as the LM339A series is available in multiple form factors including SOP14 and TSSOP14. Confirm the ordering suffix corresponds to the tape and reel quantity specified in the order information table. Ensure the component meets RoHS compatibility standards if required by the manufacturing process.
Selection Notes
Select this component when a quad comparator configuration is needed with low static power dissipation. The wide supply voltage range accommodates various system architectures. Verify that the open-drain output requirement aligns with the pull-up resistor strategy in the target circuit design.
Part Context
This part belongs to the LM331A/LM393A/LM339A family of 36-V low-power comparators. The LM339A variant specifically provides four independent channels on a single monolithic substrate. The 'TR' suffix indicates the device is supplied in a tape and reel format for automated surface-mount assembly.
