Overview
The LM211DRG4 is a single-channel analog comparator manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 3.5 V to 30 V and draws a typical operating current of 6 mA. The device features a differential input type with open collector and emitter outputs capable of sourcing up to 50 mA per channel. Key electrical specifications include a response time of 115 ns, an input offset voltage (Vos) of 3 mV, and an input bias current (Ib) of 75 nA. It functions reliably across a temperature range from -40°C to +85°C.
Feature Summary
- Features strobed differential comparison capability for precise signal detection.
- Provides versatile output configuration with both open collector and open emitter terminals.
- Supports wide single or dual power supply operation for flexible system integration.
Applications
- Voltage monitoring circuits
- Logic interface conversion
- Zero-crossing detection
Procurement Notes
Verify the specific suffix G4 indicates lead-free RoHS compliance when ordering. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental conditions. Check datasheet for proper pull-up resistor selection given the open-collector/open-emitter output structure. Validate that the 50 mA output current capacity suits your load requirements.
Selection Notes
Select this component when a single high-speed comparator with strobe functionality is required. Consider the 115 ns response time for timing-sensitive applications. Evaluate the 3 mV input offset voltage for accuracy needs. Compare against LM211 variants if different packaging or temperature ranges are needed. Ensure the 3.5 V minimum supply voltage aligns with your system power rails.
Part Context
This part belongs to the LM211 series of comparators from Texas Instruments. It shares functional similarities with other members like LM211DR but differs in packaging and reel specifications. The DRG4 designation specifically denotes the tape-and-reel format in an SOIC-8 package. It is distinct from operational amplifiers like the LM224 series due to its comparator architecture.
Replacement Considerations
LM211DR is a compatible alternative with identical electrical characteristics but may differ in packaging format.
