Overview
The LM2901AVQDRG4 is a quad differential comparator manufactured by Texas Instruments, designed for automotive and industrial applications. It features an SOIC-14 surface-mount package with 14 pins. The device operates on single or dual power supplies, supporting typical voltages from 3V to 28V for single supply and ±3V to ±15V for dual supply configurations. Key electrical parameters include a typical response time of 1.3µs, a typical voltage gain of 100 dB, and an open-collector output type. It functions within a temperature range of -40°C to +125°C.
Feature Summary
- Quad differential architecture providing four independent comparison channels in a compact package.
- Open-collector outputs compatible with CMOS and TTL logic families.
- Qualified for automotive environments under AEC-Q100 standards.
- Operates reliably across extended industrial temperature ranges.
Applications
- Automotive level detection systems
- Industrial low-level sensing circuits
- Memory application interfaces
Procurement Notes
Verify the specific suffix 'AVQDRG4' against official Texas Instruments documentation to confirm automotive qualification (AEC-Q100) and RoHS compliance status. Ensure the ordering part number matches the required package variant and temperature grade before procurement. Cross-reference datasheet revisions to validate current manufacturing availability and pinout consistency.
Selection Notes
Select this component when multiple differential comparisons are required in space-constrained designs. The open-collector output allows flexible interfacing with various logic levels. Consider the 1.3µs response time for speed requirements. Verify that the input common-mode voltage range includes ground potential if single-supply operation near zero volts is necessary.
Part Context
This device belongs to the LM2901 family of analog comparators. It shares functional similarities with other quad comparators but is distinguished by its automotive-grade qualification and differential input structure. The SOIC-14 package offers a balance between pin count and board space efficiency for multi-channel signal processing tasks.
Replacement Considerations
LM2901DR: Standard industrial grade version without automotive qualification.
