Overview
The LMX339ASD+ is a quad general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.8V to 5.5V and features an open-drain output type. The device includes internal hysteresis of 2mV for noise immunity. Key electrical parameters include a maximum input offset voltage of 7mV at 5V, a maximum input bias current of 0.25µA at 5V, and a maximum propagation delay of 600ns. It supports a wide operating temperature range from -40°C to +125°C and is housed in a 14-SOIC package.
Feature Summary
- Drop-in pin-for-pin compatible replacement for LMV339
- Internal 2mV hysteresis prevents output oscillations
- No phase reversal for overdriven inputs
- Low output saturation voltage
Applications
- Mobile Communications
- Automotive Applications
- Battery-Powered Electronics
- General-Purpose Portable Devices
Procurement Notes
Verify the component status as discontinued or obsolete through official manufacturer channels before finalizing procurement plans. Confirm that the specific ordering suffix corresponds to the required lead-free/RoHS-compliant packaging variant. Ensure compatibility with existing board layouts due to its pin-for-pin design relative to legacy parts.
Selection Notes
Select this component when low-voltage operation between 1.8V and 5.5V is required. It is suitable for designs needing internal hysteresis to handle noisy signals without external resistors. Consider the 14-SOIC package size for space-constrained applications requiring four independent comparators.
Part Context
This part belongs to the LMX331/LMX393/LMX339 series of general-purpose, low-voltage comparators. Manufactured using advanced submicron CMOS technology, the series offers advantages such as wider supply voltage ranges and improved response times compared to older BiCMOS or bipolar versions.
