Overview
The LMX339AUD+ is a quad general-purpose low-voltage comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.8V to 5.5V and supports an automotive temperature range from -40°C to +125°C. The device features open-drain outputs, input common-mode voltage range including ground, and no phase reversal for overdriven inputs. Key electrical parameters include a maximum propagation delay of 600ns at 5V, typical supply current of 120µA at 1.8V and 300µA at 5V, and input offset voltage of up to 7mV at 5V.
Feature Summary
- Drop-in pin-for-pin compatible replacement for LMV339 with improved performance characteristics
- Internal hysteresis available in H-series variants for noise immunity
- Advanced submicron CMOS technology for superior RF immunity and reduced offset
- Wide operating temperature range suitable for automotive applications
Applications
- Mobile Communications
- Automotive Applications
- Battery-Powered Electronics
- General-Purpose Portable Devices
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as product lifecycle status may vary. Ensure compatibility with existing board layouts when replacing legacy components.
Selection Notes
Select this component for low-voltage single-supply applications requiring quad comparator functionality. Consider the standard LMX339 for cost-sensitive designs or the LMX339H variant if internal hysteresis is required for noisy environments. Evaluate package constraints as it is available in TSSOP and SO formats.
Part Context
This part belongs to the LMX331/LMX393/LMX339 series of general-purpose, low-voltage comparators. These devices are designed as drop-in replacements for industry-standard LMV3xx parts but offer enhanced specifications such as wider supply voltage ranges, better CMRR/PSRR, and improved response times due to advanced CMOS fabrication techniques.
Replacement Considerations
LMX339AUD+ is a direct pin-compatible replacement for LMV339. Verify that the application does not require the internal hysteresis feature found only in the 'H' suffix variants (e.g., LMX339HAUD+) if noise immunity is critical.
