Overview
The LM2901DRG3 is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on a single or split supply voltage ranging from 2 V to 30 V. Key electrical specifications include a typical response time of 1.3 µs, an input offset voltage of 7 mV, and an operating supply current of 2.5 mA. The device features CMOS/TTL compatible outputs with a per-channel output current capability of 6 mA. It supports an extended industrial temperature range from -40 °C to +125 °C.
Feature Summary
- Quad differential architecture providing four independent comparison channels within a single integrated circuit.
- CMOS and TTL logic compatibility for direct interfacing with standard digital systems.
- Low power consumption design suitable for battery-operated and energy-efficient applications.
Applications
- Level detection circuits
- Low-level sensing systems
- Memory applications
Procurement Notes
Verify the specific datasheet revision corresponding to the LM2901DRG3 part number, as Texas Instruments documentation may group this component under broader series titles like LM2901B or LM339B. Confirm that the SOIC-14 package and RoHS-compliant 'G3' suffix match the project requirements before finalizing procurement orders.
Selection Notes
Select the LM2901DRG3 when a quad comparator configuration is required in a compact surface-mount form factor. It is appropriate for designs needing low input bias current and operation across a wide supply voltage range. Ensure the application does not require a shutdown mode, as this variant lacks that feature.
Part Context
This component belongs to the LM2901 family of analog comparators produced by Texas Instruments. It serves as a general-purpose solution for signal conditioning tasks where multiple comparison functions are needed. The device is part of a broader lineage including the LM139 and LM339 families, sharing similar functional characteristics but optimized for specific performance metrics.
Replacement Considerations
Public confirmed substitute part numbers include LM2901DR and LM2901ID. These variants share the same quad differential comparator functionality and pinout, allowing for potential interchangeability depending on specific grade or packaging availability.
