High-voltage half bridge driver

Instructions for Using the UA747MJB:

1. Supply Voltage:

   • Ensure the supply voltage is within the specified range (±7.5V to ±18V for dual supply or 15V to 36V for single supply).
   • Use appropriate decoupling capacitors (e.g., 0.1μF and 10μF) close to the power pins to stabilize the supply.

2. Input Configuration:

   • Connect the non-inverting input (pin 3) and inverting input (pin 2) as required by your circuit.
   • Use high-impedance sources to minimize the effect of input bias currents.

3. Output Configuration:

   • The output (pin 6) can swing close to the supply rails but not fully to them. Ensure the load resistance is appropriate to avoid clipping.
   • For maximum output swing, use a load resistance of at least 10kΩ.

4. Biasing and Feedback:

   • Use feedback resistors to set the gain and ensure stability.
   • For non-inverting configurations, connect the inverting input to the output through a feedback resistor and the non-inverting input to a reference voltage.

5. Temperature Considerations:

   • Operate the device within the specified temperature range to ensure reliable performance.
   • For extended temperature ranges, ensure proper thermal management to prevent overheating.

6. Protection:

   • Use external protection diodes if the inputs may exceed the supply voltage range.
   • Avoid short circuits on the output to prevent damage to the device.

7. Storage and Handling:

   • Store the device in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage the sensitive components.

By following these guidelines, you can ensure optimal performance and reliability of the UA747MJB operational amplifier in your circuits.
