LMH1982SQ/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. Additionally, it's recommended to use a low-ESR capacitor for the power supply decoupling and to keep the signal traces as short as possible.
  • The LMH1982SQ/NOPB has a specific power-up and power-down sequence requirement. The VCC pin should be powered up before the AVCC pin, and the AVCC pin should be powered down before the VCC pin. Additionally, the power supply should be ramped up and down slowly to prevent damage to the device.
  • The maximum clock frequency that can be used with the LMH1982SQ/NOPB is 100 MHz. However, the actual clock frequency that can be used may be limited by the specific application and the quality of the clock signal.
  • The LMH1982SQ/NOPB has a maximum junction temperature of 150°C. To handle thermal dissipation, it's recommended to use a heat sink or a thermal pad, and to ensure good airflow around the device. Additionally, the device should be operated within the recommended operating temperature range to prevent overheating.
  • The recommended input impedance for the LMH1982SQ/NOPB is 75 ohms. This is to ensure that the device can properly drive the input signal and to prevent signal reflections.
