Op amps are designed for linear operation with negative feedback, while comparators are optimized for open-loop operation to drive digital logic levels.

What are Linear components?
Linear ICs are the backbone of analog signal processing, performing essential tasks like amplification, filtering, and comparison. Selection hinges on balancing bandwidth, noise floor, power consumption, and input/output voltage range relative to your signal chain requirements.
How to Choose Linear Components
Selecting the right linear IC requires matching the device's transfer function to your signal's dynamic range and frequency profile.
Bandwidth vs. Power
Higher gain-bandwidth products typically demand higher quiescent current; optimize for your specific frequency needs.
Input Offset Voltage
Critical for DC precision; choose low-offset or 'zero-drift' architectures for sensor interfaces.
Rail-to-Rail Capability
Essential for low-voltage designs where signal swing must approach supply rails to maintain dynamic range.
Noise Density
Evaluate voltage and current noise specs if your application involves high-impedance sources or small signal amplification.
Common Mode Range
Ensure the input range covers your expected signal levels to prevent clipping or non-linear distortion.
