UA748CD datasheet by STMicroelectronics

UA748CD Frequently Asked Questions (FAQs)

• What is the maximum power supply voltage that can be applied to the UA748CD?
  The maximum power supply voltage that can be applied to the UA748CD is ±18V. Exceeding this voltage may cause damage to the device.
• How do I ensure stability when using the UA748CD in a unity-gain configuration?
  To ensure stability in a unity-gain configuration, add a capacitor (typically 10-100pF) between the output and the inverting input to prevent oscillations.
• What is the recommended operating temperature range for the UA748CD?
  The recommended operating temperature range for the UA748CD is -40°C to +105°C. Operating outside this range may affect the device's performance and reliability.
• Can I use the UA748CD as a comparator?
  While the UA748CD can be used as a comparator, it's not recommended due to its relatively slow slew rate (0.5V/μs) and limited output current (20mA). A dedicated comparator IC would be a better choice for most applications.
• How do I reduce noise and hum in my circuit when using the UA748CD?
  To reduce noise and hum, use proper PCB layout techniques, decouple the power supply lines with capacitors, and consider adding a noise filter or a shield around the amplifier circuit.
