INA2126UA/2K5 datasheet by Texas Instruments

INA2126UA/2K5 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the INA2126UA/2K5?
  The maximum power dissipation of the INA2126UA/2K5 is 670mW at 25°C, but it can be derated to 560mW at 85°C.
• How do I optimize the layout for the INA2126UA/2K5 to minimize noise and EMI?
  To minimize noise and EMI, keep the input traces as short as possible, use a solid ground plane, and keep the power supply traces away from the input traces. Also, use a common-mode filter capacitor between the input pins and the ground pin.
• What is the recommended input impedance for the INA2126UA/2K5?
  The recommended input impedance for the INA2126UA/2K5 is 1kΩ to 10kΩ. This ensures that the input voltage is properly divided and the amplifier operates within its specified range.
• Can I use the INA2126UA/2K5 as a single-ended amplifier?
  Yes, the INA2126UA/2K5 can be used as a single-ended amplifier by connecting the negative input to ground and using the positive input as the signal input. However, this will reduce the common-mode rejection ratio (CMRR) and increase the noise.
• How do I calculate the gain of the INA2126UA/2K5?
  The gain of the INA2126UA/2K5 can be calculated using the formula: Gain = (Rf / Rg) x (1 + (R2 / R1)), where Rf is the feedback resistor, Rg is the gain resistor, R2 is the output resistor, and R1 is the input resistor.
