INA143UA/2K5 datasheet by Texas Instruments

INA143UA/2K5 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the INA143UA/2K5?
  The maximum power dissipation of the INA143UA/2K5 is 670mW at 25°C. However, it's recommended to derate the power dissipation to ensure reliable operation.
• How do I layout the PCB to minimize noise and ensure optimal performance?
  To minimize noise and ensure optimal performance, it's recommended to follow good PCB layout practices such as separating analog and digital grounds, using a solid ground plane, and keeping the input and output traces short and symmetrical.
• What is the recommended input impedance for the INA143UA/2K5?
  The recommended input impedance for the INA143UA/2K5 is 1kΩ to 10kΩ. This ensures optimal common-mode rejection and noise performance.
• Can I use the INA143UA/2K5 for single-ended to differential conversion?
  Yes, the INA143UA/2K5 can be used for single-ended to differential conversion. However, it's recommended to use an external resistor network to convert the single-ended input to a differential signal.
• What is the maximum input voltage range for the INA143UA/2K5?
  The maximum input voltage range for the INA143UA/2K5 is ±10V. Exceeding this range may result in reduced accuracy or damage to the device.
