LMP7707MF/NOPB datasheet by Texas Instruments

LMP7707MF/NOPB Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LMP7707MF/NOPB?
  The maximum power dissipation of the LMP7707MF/NOPB is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.
• How do I ensure stability when using the LMP7707MF/NOPB in a high-gain configuration?
  To ensure stability, it's recommended to use a compensation capacitor (CC) between the output and the inverting input pins. The value of CC depends on the gain and bandwidth requirements of the application. A good starting point is to use a 10pF to 22pF capacitor.
• What is the recommended layout and routing for the LMP7707MF/NOPB to minimize noise and EMI?
  To minimize noise and EMI, it's recommended to use a star-ground configuration, keep the input and output traces short and away from each other, and use a ground plane to shield the device. Additionally, decoupling capacitors should be placed close to the power pins.
• Can I use the LMP7707MF/NOPB in a single-supply configuration?
  Yes, the LMP7707MF/NOPB can be used in a single-supply configuration. However, the input common-mode voltage range is limited to VCC-1.5V to VCC+0.5V. To ensure proper operation, the input signal should be biased within this range.
• How do I handle the ESD protection of the LMP7707MF/NOPB?
  The LMP7707MF/NOPB has built-in ESD protection, but it's still recommended to follow proper ESD handling procedures during assembly and testing. Additionally, it's recommended to use ESD protection devices, such as TVS diodes, at the input and output pins.
