Overview
The LM393LVQDDFRQ1 is an automotive-grade dual differential analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features rail-to-rail input capability with open-drain outputs. The device supports a maximum operating temperature of +125°C and includes two channels per package. Key electrical specifications include a propagation delay of 600 ns, a quiescent current of 25 µA, and an input offset voltage of 2 mV. It is housed in an SOIC-8 surface-mount package.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 standards for sustained operation in vehicle environments
- Low-voltage operation optimized for battery-powered systems with minimal power consumption
- Rail-to-rail input stage enables accurate signal detection across the full supply voltage range
Applications
- Automotive sensor signal conditioning
- Battery management system monitoring
- Vehicle thermal protection circuits
Procurement Notes
Verify that the specific suffix QDDFRQ1 confirms automotive qualification and tape-and-reel packaging configuration. Ensure the component meets required AEC-Q100 grade specifications for your target application environment. Cross-reference the manufacturer datasheet for exact ordering codes and availability status before finalizing procurement plans.
Selection Notes
Select this component when low supply voltage operation below 3.3 V is required alongside automotive durability. The rail-to-rail inputs simplify interface design with various sensors. Verify that the 600 ns response time aligns with system timing requirements and that the SOIC-8 package fits the PCB layout constraints.
Part Context
This part belongs to the LM393LV family of low-voltage comparators designed specifically for automotive applications. It provides dual-channel performance in a compact footprint, serving as a robust alternative to standard industrial comparators in harsh vehicle environments where power efficiency and wide temperature tolerance are critical.
Replacement Considerations
Direct replacements must match the LM393LV series characteristics and automotive qualification. Verify pin compatibility and electrical parameters such as supply voltage range and output type before substitution.
