Overview
The LM211QDG4 is a high-speed differential comparator manufactured by Texas Instruments, designed for automotive applications. It features a single channel with open collector and emitter outputs capable of sourcing up to 50 mA. The device operates within a supply voltage range of 3.5 V to 30 V and consumes 6 mA of quiescent current. Key electrical specifications include an input offset voltage of 3 mV, an input bias current of 75 nA, and a response time of 115 ns. It supports a common-mode voltage range from -14.7 V and functions reliably across an extended temperature range of -40°C to +125°C.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards
- Differential input configuration with strobe functionality
- Versatile output interface supporting multiple logic families
Applications
- Automotive electronic control units
- High-speed signal processing circuits
- Voltage monitoring systems in vehicles
Procurement Notes
Verify the specific suffix 'DG4' against official Texas Instruments documentation to confirm package type and compliance status. Ensure the component meets AEC-Q100 requirements for your target application. Cross-reference the datasheet revision history for any recent design or assembly updates that may affect compatibility.
Selection Notes
Select this component when automotive qualification is mandatory and differential comparison with strobing is required. Consider the 115 ns response time and 50 mA output drive capability for load requirements. Verify that the SOIC-8 package fits the board layout constraints and that the operating temperature range aligns with the environmental conditions.
Part Context
This part belongs to the LM211 series of comparators, which are known for high speed and low power consumption. The 'Q' designation indicates it is qualified for automotive use, while 'DG4' specifies the SOIC-8 package and lead-free construction. It serves as a specialized variant within the broader LM211 family tailored for harsh automotive environments.
Replacement Considerations
LM211QDRQ1: Same automotive grade and function but in SOIC-8 (DW) package; verify pinout compatibility if footprint differs.
