Overview
The LM2903AVQPWR is a dual differential voltage comparator from Texas Instruments, designed for single-supply operation with a wide voltage range. It features an open-collector output and includes ground in its common-mode input voltage range. The device operates within a supply voltage of 2 V to 32 V and draws a typical quiescent current between 1 mA and 2.5 mA. It exhibits a response time of 1.3 µs and maintains an input offset voltage of 4 mV. The component functions reliably across an extended temperature range from -40°C to +125°C and is housed in an 8-pin TSSOP package.
Feature Summary
- Dual differential voltage comparison capability optimized for single-supply applications
- Open-collector output structure allowing flexible interfacing and parallel operation
- Extended industrial temperature range ensuring reliable performance in harsh environments
Applications
- Overvoltage and undervoltage monitoring circuits
- Window comparator configurations
- Threshold detection systems
Procurement Notes
Verify the specific suffix 'AVQPWR' against official Texas Instruments documentation to confirm exact grade and packaging specifications. Ensure compatibility with target PCB footprint and thermal requirements. Confirm that the open-collector output configuration aligns with system pull-up resistor designs. Validate that the operating voltage range meets application demands before integration.
Selection Notes
Select this component when dual independent comparators are required in a compact surface-mount package. The open-collector output necessitates external pull-up resistors, which must be accounted for in the design phase. Consider the 1.3 µs propagation delay for timing-sensitive applications. Verify that the 4 mV input offset voltage meets the precision requirements of the intended sensing circuit.
Part Context
This part belongs to the LMx93/LM2903 series of dual voltage comparers. These devices are distinct from operational amplifiers as they are optimized for fast switching rather than linear operation. The series supports a broad range of single-supply voltages and features inputs that include ground potential, facilitating direct connection to various sensor outputs without additional biasing.
Replacement Considerations
LM2903AVQDRQ1: Automotive-grade alternative with SOIC-8 package.
