Overview
The LM2903QDGKRQ1 is an automotive-grade analog comparator manufactured by Texas Instruments. It features a dual differential input configuration housed in an 8-pin VSSOP package. The device operates within a supply voltage range of 2 V to 30 V and supports single or dual power supplies. Key electrical parameters include a typical response time of 1.3 µs, a maximum input offset voltage (Vos) of 15 mV, and an input bias current (Ib) of 250 nA. It functions without a shutdown mode and maintains operation across a temperature range from -40°C to +150°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability
- Dual differential voltage comparison capability with open collector/drain outputs
- Extended high-temperature operational range up to 150°C
Applications
- Automotive electronic control units requiring signal threshold detection
- Voltage monitoring circuits in vehicle power systems
- Temperature sensing interfaces utilizing differential input comparison
Procurement Notes
Verify the specific suffix 'DGKRQ1' to confirm the VSSOP-8 package and reel packaging format. Ensure the component meets AEC-Q100 grade requirements for your target automotive application. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision status before integration into production designs.
Selection Notes
Select this component when automotive reliability and extended temperature performance are critical. The VSSOP-8 package offers space efficiency for compact board layouts. Consider the 1.3 µs response time and 15 mV offset voltage specifications against system timing and accuracy requirements. Verify that the open collector output interface aligns with the downstream logic or pull-up network design.
Part Context
This device belongs to the LM2903-Q1 series, which includes standard and B-grade variants. The Q1 designation indicates automotive qualification. The DGKR suffix specifies the VSSOP-8 tape and reel packaging. This series provides a robust solution for general-purpose comparison tasks in demanding environments where standard commercial grade components may not suffice.
Replacement Considerations
LM2903AVQDRQ1: Enhanced version with lower offset voltage and SOIC-8 package.
