Overview
The LM319MWA is a high-speed dual comparator from Texas Instruments, designed for automotive applications. It features an excellent speed-to-power combination with a typical response time of 80 ns at ±15 V supply. The device operates on single supplies from 5 V to 36 V or dual supplies from ±2.5 V to ±18 V. It has a maximum input offset voltage of 8 mV and a maximum input bias current of 1 µA. The component dissipates up to 500 mW and functions within a temperature range of -55 °C to 125 °C.
Feature Summary
- Qualified for automotive applications
- High-speed response capability
- Low input offset voltage
- Open collector output compatibility
Applications
- Automotive signal processing systems
- Industrial automation devices
- Power supply control circuits
Procurement Notes
Verify the specific suffix 'MWA' indicates automotive qualification and die package form factor. Confirm the operating temperature range extends to -55 °C, which differs from commercial variants. Ensure the source document explicitly supports the automotive grade designation before procurement.
Selection Notes
Select this variant when automotive reliability standards are required. The die package format necessitates specific mounting considerations compared to standard SOIC packages. Verify that the open-collector output interface matches the system logic requirements without additional pull-up components.
Part Context
This component belongs to the LM319 family of high-speed dual comparators manufactured by Texas Instruments. While other versions like LM319M/NOPB use SOIC-14 packages, the MWA suffix denotes a die package optimized for automotive environments. It shares core electrical characteristics with the broader LM319 series but targets stricter environmental conditions.
Replacement Considerations
LM319MX/NOPB offers similar electrical performance in a surface-mount package. LM319N-NOPB provides through-hole mounting options. Verify pinout and thermal management requirements when substituting these package variants.
