Overview
The LP311DG4 is a high-speed, differential comparator manufactured by Texas Instruments. It operates within a supply voltage range of 3.5V to 30V for single supplies or ±1.75V to ±15V for dual supplies. The device features a maximum input offset voltage of 7.5mV at ±15V and a maximum input bias current of 0.1µA at ±15V. It utilizes an 8-SOIC package with a width of 3.90mm and supports surface-mount installation. The component functions as a standard general-purpose comparator with open-collector and open-emitter outputs.
Feature Summary
- Differential input configuration for precise signal comparison
- Open-collector and open-emitter output options for flexible interfacing
- High-speed operation capabilities for rapid response times
Applications
- General-purpose voltage monitoring circuits
- Zero-crossing detection systems
- Logic level translation interfaces
Procurement Notes
Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the RoHS compliance status matches current regulatory requirements for your target market. Check for any recent Product Change Notifications (PCNs) regarding assembly sites or material changes before finalizing procurement orders.
Selection Notes
Select this component when a low-cost, high-speed comparator with multiple output types is required. Ensure the operating temperature range of 0°C to 70°C aligns with the system environment. Consider the 7.5mV offset voltage specification if high precision is necessary for the application.
Part Context
This part belongs to the LP211/LP311 family of comparators from Texas Instruments. It shares functional similarities with the LM311 series but offers specific performance characteristics tailored for general-purpose applications. The DG4 suffix indicates a lead-free, RoHS-compliant variant in an 8-SOIC package.
Replacement Considerations
The LM311DRG4 is a documented substitute within the same product family. Verify pin compatibility and electrical parameter alignment before substitution.
