INA204AIDGST datasheet by Texas Instruments

INA204AIDGST Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the input pins?
  The maximum voltage that can be applied to the input pins is ±25V, but it's recommended to keep it within the common-mode voltage range of ±12V to ensure accurate measurements.
• How do I calculate the gain error of the INA204?
  The gain error can be calculated using the formula: Gain Error (%) = (Vout / (G x Vin)) x 100, where Vout is the output voltage, G is the gain, and Vin is the input voltage.
• What is the purpose of the REF pin, and how do I connect it?
  The REF pin is the reference voltage input for the internal amplifier. It should be connected to a stable voltage source, typically the same as the supply voltage, to ensure accurate measurements.
• Can I use the INA204 with a single-supply voltage?
  Yes, the INA204 can be used with a single-supply voltage, but the input common-mode voltage range will be limited to VCC - 1.5V to VCC + 0.5V. Additionally, the output voltage swing will be reduced.
• How do I layout the PCB to minimize noise and ensure accurate measurements?
  To minimize noise and ensure accurate measurements, it's recommended to follow good PCB layout practices, such as separating analog and digital signals, using a solid ground plane, and keeping the input and output traces short and shielded.
