Instructions for Use:

1. Supply Voltage:

   • Ensure the supply voltage is within the range of 2.7V to 36V.
   • Connect the positive supply (V_CC) to the appropriate pin and the negative supply (GND) to the ground.

2. Quiescent Current:

   • The quiescent current is approximately 1000 μA per channel. This value should be considered when designing power-efficient circuits.

3. Input Offset Voltage:

   • The input offset voltage is typically 10 μV and can vary up to 35 μV. Use this information to calibrate or compensate for any offsets in your circuit.

4. Input Bias Current:

   • The input bias current is typically 5 pA. This low value makes the ADA4522-4ARZ suitable for high-impedance applications.

5. Input Voltage Noise:

   • The input voltage noise is typically 2.9 nV/√Hz. This is important for low-noise applications.

6. Slew Rate:

   • The slew rate is typically 1.5 V/μs. This limits the maximum rate at which the output can change and should be considered for fast signal processing.

7. Gain Bandwidth Product:

   • The gain bandwidth product is typically 1.5 MHz. This determines the maximum gain that can be achieved for a given frequency.

8. Common Mode Rejection Ratio (CMRR):

   • The CMRR is typically 110 dB, indicating good rejection of common-mode signals.

9. Power Supply Rejection Ratio (PSRR):

   • The PSRR is typically 110 dB, indicating good rejection of power supply variations.

10. Output Voltage Swing:

    • The output voltage swing is typically 1.2V from the rail. Ensure that the output signal does not exceed this limit to avoid distortion.

11. Operating Temperature:

    • The operating temperature range is from -40°C to 125°C. Ensure that the ambient temperature stays within this range to maintain reliable operation.

Additional Notes:

• Always refer to the datasheet for detailed specifications and application notes.
• Proper decoupling capacitors should be used near the power supply pins to ensure stable operation.
• For optimal performance, use a well-designed PCB layout with short traces and proper grounding.
