Overview
The LM211PWR is a single high-speed comparator manufactured by Texas Instruments, housed in an 8-TSSOP surface-mount package. It operates on a supply voltage range of 3.5V to 30V (single) or ±1.75V to ±15V (dual). Key electrical specifications include a maximum input offset voltage of 3mV at ±15V, a typical output current of 50mA, and a maximum quiescent current of 6mA. The device supports DTL, MOS, open-collector, open-emitter, RTL, and TTL outputs, functioning within a temperature range of -40°C to 85°C.
Feature Summary
- High-speed response capability for rapid signal comparison
- Versatile output compatibility with multiple logic families including DTL, MOS, and TTL
- Wide single or dual power supply operation range
Applications
- Voltage threshold detection circuits
- Zero-crossing detectors
- Simple analog-to-digital conversion interfaces
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the 8-TSSOP package variant when sourcing. Confirm RoHS compliance status as indicated by the manufacturer's current documentation. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement.
Selection Notes
Select this component when a single-channel comparator with wide supply voltage flexibility is required. Consider the 50mA output drive capability for direct interfacing with low-impedance loads. Evaluate the 3mV input offset voltage specification against the precision needs of the specific circuit design.
Part Context
This part belongs to the LMx11 series of comparators from Texas Instruments. It serves as a general-purpose solution for applications requiring fast switching between analog signals. The TSSOP packaging facilitates automated assembly in compact electronic designs compared to through-hole alternatives.
Replacement Considerations
Check for pin-compatible alternatives such as the LM311 or LM339 if system redesign is necessary. Verify that substitute components maintain the required output logic compatibility and supply voltage ranges.
