LME49726MY/NOPB datasheet by Texas Instruments

LME49726MY/NOPB Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LME49726MY/NOPB?
  The maximum power dissipation of the LME49726MY/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 LME49726MY/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 a 10pF to 22pF capacitor.
• What is the recommended layout and routing for the LME49726MY/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 LME49726MY/NOPB in a single-supply configuration?
  Yes, the LME49726MY/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 sensitivity of the LME49726MY/NOPB?
  The LME49726MY/NOPB is a sensitive device and requires proper handling to prevent ESD damage. It's recommended to use an ESD wrist strap or mat, and to handle the device by the body or pins, rather than the leads.
