LM741 Operational Amplifier
The LM741 is a general-purpose single operational amplifier with high gain and internal frequency compensation. It is one of the most widely used op-amps in analog electronics due to its simplicity, availability, and reliability.
Specifications:
- Single op-amp in an 8-pin DIP
- Dual power supply: ±10V to ±22V (typical ±15V)
- Internally frequency compensated
- Large voltage gain: 200,000 (typical)
- Input Offset Voltage: 1 mV typical
- Input Bias Current: 80 nA typical
- Output Short-Circuit Current: ±25 mA max
- Power Dissipation: 500 mW (DIP-8 package, at 25°C)
- Slew Rate: 0.5 V/µs
- Common-Mode Rejection Ratio (CMRR): 90 dB typical
- Operating Temperature Range: 0°C to +70°C (LM741C)
Applications:
- General-purpose amplification
- Analog computation
- Signal conditioning
- Integrator and differentiator circuits
- Audio preamplifiers
- Comparator circuits (non-critical applications)
