LM158DT datasheet by STMicroelectronics

LM158DT Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM158DT?
  The maximum power dissipation of the LM158DT is 1.4W, but it can be increased to 2.5W if the device is mounted on a suitable heat sink.
• Can I use the LM158DT as a voltage regulator?
  Yes, the LM158DT can be used as a voltage regulator, but it's not recommended as it's primarily designed as an operational amplifier. If you need a voltage regulator, consider using a dedicated voltage regulator IC like the 78L05 or 79L05.
• What is the input impedance of the LM158DT?
  The input impedance of the LM158DT is typically around 2MΩ, but it can vary depending on the specific application and circuit configuration.
• Can I use the LM158DT in a high-frequency application?
  The LM158DT is not suitable for high-frequency applications above 100kHz due to its limited bandwidth and slew rate. For high-frequency applications, consider using a more specialized op-amp like the OP07 or OP27.
• How do I ensure stability in a circuit using the LM158DT?
  To ensure stability in a circuit using the LM158DT, make sure to follow proper layout and grounding techniques, use decoupling capacitors, and avoid high-gain configurations. Also, consider adding a compensation capacitor between the output and the inverting input to improve stability.
