Key Features:

• Two Independent Differential Amplifiers: Each differential amplifier has two inputs (inverting and non-inverting) and one output, designed for differential operation.
• Integrated Constant Current Transistors: Provide stable biasing for the differential amplifiers, improving linearity and reducing temperature effects.
• Monolithic Substrate: Ensures good matching between internal components, enhancing accuracy and stability.
• High Input Impedance: Suitable for interfacing with low-power signal sources.
• Low Noise: Designed for low-noise performance, ideal for sensitive applications like instrumentation and communications.
• Single or Dual Supply Operation: Flexible power supply options for circuit design.

Typical Applications:

• Instrumentation Amplifiers: Amplifies small differential signals from sensors or transducers.
• ADC Front-Ends: Signal conditioning before analog-to-digital conversion.
• Demodulation Circuits: Ideal for modulation/demodulation in communication systems.
• Active Filters: Can be used to design active filters such as bandpass or notch filters.
• Professional Audio Systems: Suitable for high-quality audio applications due to low distortion and noise.

Technical Specifications (Typical):

• Supply Voltage: ±5V to ±15V (dual supply) or +10V to +30V (single supply).
• Input Offset Voltage: Low offset voltage for precision applications.
• Gain Bandwidth Product: Suitable for moderate-frequency applications.
• Operating Temperature Range: -55°C to +125°C (military grade), 0°C to +70°C (commercial grade).
