LM741 Comparator / Operational Amplifier

The LM741 Operational Amplifier is a general-purpose op-amp for amplification, filtering, and analog signal processing. It has been the standard teaching op-amp for decades and remains useful for basic analog circuit design.

Key Features

• General-purpose op-amp
• High open-loop gain (~200,000)
• Wide supply range (±5V to ±18V)
• Short-circuit protection
• 8-pin DIP package
• Offset null capability
• Low cost and widely available

Technical Specifications

Applications

• Amplifier circuits
• Active filters
• Comparators
• Signal conditioning
• Oscillators
• Analog computation

Important Notes

• 741 requires ± dual supply for many applications
• Input offset voltage may need nulling for precision circuits
• Limited bandwidth (1MHz) – not for high-frequency
• Low slew rate limits large-signal high-frequency performance
• Modern op-amps (TL071, LM358) outperform 741 in most specs
• Output cannot reach supply rails (limited output swing)
