Instructions for Use

1. Supply Voltage:

   • The AD820AR can operate over a wide supply voltage range from 2.7V to 36V.
   • Ensure that the supply voltage is within this range to avoid damage to the device.

2. Supply Current:

   • The typical supply current is 1.3mA. This value should be considered when designing the power supply circuitry.

3. Input Offset Voltage:

   • The input offset voltage is typically 25μV. This parameter is important for precision applications where small signal levels are involved.

4. Input Bias Current:

   • The input bias current is typically 0.5nA. This low value helps minimize errors in high-impedance circuits.

5. Input Voltage Range:

   • The input voltage range is from -0.3V to V_CC + 0.3V. Ensure that the input signals do not exceed these limits to prevent damage or incorrect operation.

6. Output Voltage Swing:

   • The output voltage swing is from -0.3V to V_CC - 0.3V. This range should be considered when selecting load resistors and designing the output stage.

7. Bandwidth:

   • The typical bandwidth is 1.2MHz. This parameter is crucial for determining the maximum frequency at which the op-amp can effectively amplify signals.

8. Slew Rate:

   • The typical slew rate is 0.4V/μs. This parameter is important for applications involving large signal swings or high-frequency signals.

9. Common-Mode Rejection Ratio (CMRR):

   • The typical CMRR is 98dB. This high value indicates good rejection of common-mode signals, which is beneficial in noisy environments.

10. Power-Supply Rejection Ratio (PSRR):

    • The typical PSRR is 94dB. This high value indicates good rejection of power supply noise, which helps maintain signal integrity.

11. Gain-Bandwidth Product (GBP):

    • The typical GBP is 1.2MHz. This parameter is useful for determining the gain settings for the op-amp in different configurations.

12. Operating Temperature:

    • The operating temperature range is from -40°C to 85°C. Ensure that the ambient temperature is within this range to guarantee reliable operation.

Additional Notes:

• Always refer to the datasheet for the most accurate and detailed information.
• Proper decoupling capacitors should be used near the power supply pins to ensure stable operation.
• For high-precision applications, consider using matched resistor networks to minimize errors.
