Overview
The LM2901AQT14-13 is an automotive-compliant quad differential voltage comparator manufactured by Diodes Incorporated. It features four independent precision comparators with a very low input offset voltage of 1mV typical at +25°C and 4mV maximum over the full temperature range. The device operates from a single supply of 2V to 36V or dual supplies of ±1.0V to ±18V, drawing a supply current of 0.9mA typical at VCC=5V. It utilizes a TSSOP-14 package and supports direct interfacing with TTL and CMOS logic families.
Feature Summary
- Automotive Grade 1 qualification compliant with AEC-Q100 standards
- Very low input offset voltage specification for high precision applications
- Wide power supply range supporting both single and split supply configurations
- Output voltage compatible with standard TTL, MOS, and CMOS logic levels
Applications
- Automotive electronic systems requiring specific change control
- Precision voltage monitoring circuits
- Logic interface adapters between analog sensors and digital controllers
- Threshold detection in battery management systems
Procurement Notes
Verify that the component matches the specified LM2901AQT14-13 part number exactly. Confirm the presence of the 'A' suffix indicating low offset voltage characteristics and the 'Q' suffix denoting automotive grade qualification. Ensure the TSSOP-14 package type aligns with your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when high precision voltage comparison is required in automotive environments. The 'A' variant provides tighter offset voltage tolerances compared to the standard LM2901Q. Consider the open-collector output structure which requires an external pull-up resistor for proper logic level generation. Verify that the operating temperature range meets your system's environmental constraints.
Part Context
This device belongs to the LM2901Q/LM2901AQ series of automotive-compliant comparators. It shares the same pinout and general functionality as the non-automotive LM2901A but includes rigorous qualification testing for automotive reliability. The quad configuration allows multiple comparisons within a single integrated circuit, reducing board space compared to discrete solutions.
Replacement Considerations
LM2901QT14-13 (Standard grade, higher offset voltage)
FAQ
What is the maximum differential input voltage allowed?
The differential input voltage can equal the power supply voltage, up to 36V, without damaging the device.
Can the inputs go negative relative to ground?
The common-mode input voltage range includes ground. However, inputs should not go more than 0.3V below the negative supply rail to avoid damage.
Is hysteresis required for stable operation?
Hysteresis is recommended to prevent oscillation caused by stray capacitance coupling between the output and inputs during state transitions.
