4.5MHz, BiMOS Operational Amplifier with MOSFET Input/Bipolar Output

Instructions for Using CA3140MZ:

1. Supply Voltage:

   • The CA3140MZ can operate with a supply voltage ranging from 3V to 36V. Ensure that the supply voltage is within this range to avoid damage.

2. Input Voltage Range:

   • The input voltage should be within the range of -0.5V to Vcc + 0.5V. Exceeding these limits can cause damage to the device.

3. Output Voltage Swing:

   • The output voltage swing is from 0V to Vcc - 2.5V. This means the output cannot reach the full supply voltage.

4. Quiescent Current:

   • The quiescent current is typically 150 μA. This is the current drawn by the op-amp when it is not driving any load.

5. Input Bias Current:

   • The input bias current is typically 50 pA. This is the current required to bias the input transistors.

6. Input Offset Current:

   • The input offset current is typically 5 pA. This is the difference between the two input bias currents.

7. Input Offset Voltage:

   • The input offset voltage is typically 5 mV. This is the voltage difference between the two inputs when the output is zero.

8. Slew Rate:

   • The slew rate is typically 0.5 V/μs. This is the maximum rate at which the output voltage can change.

9. Bandwidth (G=1):

   • The bandwidth with a gain of 1 is typically 1.2 MHz. This is the frequency at which the gain drops to -3 dB.

10. Common Mode Rejection Ratio (CMRR):

    • The CMRR is typically 90 dB. This indicates the ability of the op-amp to reject common-mode signals.

11. Power Supply Rejection Ratio (PSRR):

    • The PSRR is typically 90 dB. This indicates the ability of the op-amp to reject variations in the power supply.

12. Operating Temperature Range:

    • The operating temperature range is from -40°C to 125°C. Ensure that the device operates within this temperature range to maintain performance.

13. Storage Temperature Range:

    • The storage temperature range is from -65°C to 150°C. Store the device within this range to prevent damage.

Additional Notes:

• Always use appropriate decoupling capacitors (e.g., 0.1 μF ceramic capacitors) close to the power supply pins to filter out noise.
• Ensure that the input and output signals are within the specified ranges to avoid distortion or damage.
• When designing circuits, consider the typical values provided in the table for optimal performance.
