Overview
The LM2903BQDRQ1 is an automotive-grade, dual differential analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 36 V and features open collector/open drain outputs. The device exhibits a typical response time of 1 µs and a maximum input offset voltage of 4 mV. It draws between 600 µA and 800 µA in quiescent current with an input bias current of 25 nA. Designed for surface-mount installation in SOIC-8 packages, it supports operation across temperatures from -40 °C to +125 °C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
- Dual-channel differential comparison architecture providing two independent comparators in a single package.
- Wide single or dual power supply capability supporting flexible system integration.
Applications
- Automotive electronic control units requiring high-reliability signal monitoring.
- Voltage level detection circuits in automotive sensor interfaces.
- Over-voltage and under-voltage protection systems in vehicle power distribution networks.
Procurement Notes
Verify the specific suffix QDRQ1 against the manufacturer's official datasheet to confirm the exact package variant and temperature grade. Ensure compatibility with automotive quality management systems (IATF 16949) if required for your assembly process. Cross-reference the ordering part number with the latest Texas Instruments documentation to avoid discrepancies in pinout or electrical specifications due to potential design changes.
Selection Notes
Select this component when automotive reliability is mandatory and dual comparator functionality is needed. The wide supply voltage range accommodates various automotive bus architectures. Consider the open-drain output type for necessary pull-up resistor implementation. Verify that the 1 µs response time meets the speed requirements of your specific application signals compared to faster alternatives.
Part Context
This part belongs to the LM2903-Q1 family of dual comparators designed specifically for automotive applications. It shares functional similarities with the commercial LM2903 but includes enhanced testing and qualification processes to meet automotive industry standards. The B suffix typically denotes improved performance characteristics such as lower offset voltage compared to standard variants.
