  • Large signal voltage gain of 106 dB
  • Wide power supply range: ±10V to ±15V
  • Short-circuit protection
  • Offset-voltage null capability
  • Low input bias current: 80 nA (typical)
  • High input impedance: 2 MΩ (typical)
  • Low power consumption
  • Compatible with standard LM741 pin configurations

Technical Specifications:

  • Input Offset Voltage: 1 mV (typical)
  • Input Bias Current: 80 nA (typical)
  • Input Impedance: 2 MΩ (typical)
  • Output Impedance: 75Ω (typical)
  • Large Signal Voltage Gain: 106 dB (typical)
  • Unity-Gain Bandwidth: 1 MHz (typical)
  • Slew Rate: 0.5 V/µs (typical)
  • Common Mode Rejection Ratio (CMRR): 90 dB (typical)
  • Power Supply Rejection Ratio (PSRR): 96 dB (typical)
  • Operating Temperature Range: 0°C to +70°C
  • Package Types: 8-pin PDIP, SOIC, TO-99

Applications:

  • Signal conditioning
  • Voltage followers
  • Integrators and differentiators
  • Active filters
  • General-purpose analog applications
  • Audio amplifiers
  • Industrial controls
  • Data acquisition systems

Usage:

  1. Connection:
    • Connect the power supply to the V+ and V- pins.
    • Connect the input signal to the inverting (−) or non-inverting (+) input pin.
    • Connect the output to the desired load or next stage of the circuit.
    • Use the offset null pins if necessary to adjust the input offset voltage.
  2. Configuration:
    • Configure the op-amp in the desired configuration (e.g., voltage follower, inverting amplifier, non-inverting amplifier) by connecting the appropriate feedback components.
    • Adjust the gain and frequency response using external resistors and capacitors.
  3. Protection:
    • Use proper decoupling capacitors on the power supply lines to reduce noise and improve stability.
    • Ensure the op-amp is within the recommended supply voltage range to prevent damage.

Caution:

  • Observe proper handling procedures to avoid electrostatic discharge (ESD) damage.
  • Ensure the input signals are within the common-mode voltage range to prevent improper operation.
  • Avoid exceeding the maximum ratings for voltage, current, and temperature.
