Overview
The LM2903BQDGKRQ1 is an automotive-grade dual differential comparator from Texas Instruments, part of the LM2903B-Q1 family. It operates on a single or dual supply ranging from 2V to 36V within an ambient temperature range of -40°C to +125°C. The device features low quiescent current (600µA typical), low input bias current (3.5nA typical), and low input offset voltage (±0.37mV typical). It provides open-drain outputs compatible with TTL, MOS, and CMOS logic levels.
Feature Summary
- Qualified for automotive applications under AEC-Q100 standards
- Enhanced electrostatic discharge protection with improved HBM rating
- Low power consumption independent of supply voltage
- Wide common-mode input voltage range including ground
Applications
- Hybrid electric vehicle and electric vehicle power trains
- Automotive infotainment systems and instrument clusters
- Body control modules
- Industrial automation equipment
- Consumer appliance control circuits
Procurement Notes
Verify the specific package variant DGK corresponds to the VSSOP-8 form factor required for your PCB layout. Confirm that the AEC-Q100 Grade 1 qualification meets your system's reliability targets. Ensure design margins account for the specified operating temperature range of -40°C to +125°C during final validation.
Selection Notes
Select this component when high voltage tolerance up to 36V is required alongside low power operation. The B-series offers superior offset voltage and ESD performance compared to standard variants. Consider the open-drain output architecture if level shifting between different logic voltage domains is necessary for your microcontroller interface.
Part Context
This device belongs to the LM2903-Q1 family, representing the next-generation evolution of industry-standard comparators. It serves as a drop-in replacement for legacy parts while providing enhanced electrical characteristics such as lower propagation delay and improved noise immunity. The family supports various packaging options to accommodate diverse board space constraints in modern electronic designs.
