Overview
The LM2901DRG4 is a quad differential analog comparator manufactured by Texas Instruments, housed in a 14-SOIC surface-mount package. It operates on a supply voltage range of 2 V to 30 V with a typical operating supply current of 2.5 mA. The device features a response time of 1.3 µs and an input offset voltage (Vos) of 7 mV. Input bias current (Ib) is specified at 250 nA, while input offset current (Ios) is 50 nA. It supports CMOS and TTL output types and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Quad differential configuration for multi-channel signal comparison
- Compatible with both CMOS and TTL logic families
- Wide single-supply voltage operation capability
Applications
- General-purpose analog signal processing
- Voltage level detection circuits
- Over-voltage protection systems
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Ensure the SOIC-14 package dimensions match the target PCB footprint requirements. Confirm that the 1.3 µs response time meets the system timing constraints for the intended application environment.
Selection Notes
Select this component when a quad comparator solution is required with low power consumption and wide supply voltage tolerance. The 14-SOIC package offers a compact form factor suitable for space-constrained designs. Consider the 7 mV input offset voltage specification for applications requiring moderate precision without the need for external trimming or chopper-stabilized amplifiers.
Part Context
This part belongs to the LM2901 series of analog comparators from Texas Instruments. It serves as a general-purpose alternative to other quad comparator devices in the industry. The 'G4' suffix typically indicates a lead-free and RoHS-compliant variant of the standard LM2901DR device, maintaining identical electrical characteristics while adhering to environmental standards.
Replacement Considerations
LM2901DR is the direct non-RoHS equivalent. LM2901AVQDRG4Q1 is a qualified automotive-grade alternative with improved speed (300 ns) and lower offset (2 mV). LM339N is a pin-compatible legacy option but may differ in performance specifications.
