INA194AIDBVT datasheet by Texas Instruments

INA194AIDBVT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the INA194AIDBVT can handle?
  The INA194AIDBVT can handle input voltages up to 80V, but it's recommended to limit the input voltage to 60V to ensure accurate measurements.
• How do I ensure accurate current measurements with the INA194AIDBVT?
  To ensure accurate current measurements, make sure to use a sense resistor with a low temperature coefficient, keep the sense resistor close to the INA194AIDBVT, and use a low-noise power supply.
• What is the effect of temperature on the INA194AIDBVT's accuracy?
  The INA194AIDBVT's accuracy can be affected by temperature changes. The device has a specified temperature range of -40°C to 125°C, and the accuracy may degrade at extreme temperatures.
• Can I use the INA194AIDBVT for high-frequency current measurements?
  The INA194AIDBVT is designed for low-frequency current measurements (up to 1 kHz). For high-frequency measurements, consider using a different device or adding external filtering to reduce noise.
• How do I layout the PCB to minimize noise and ensure accurate measurements with the INA194AIDBVT?
  To minimize noise, keep the sense resistor and INA194AIDBVT close together, use a ground plane, and avoid running digital signals near the analog signals. Also, use a low-noise power supply and decouple the power supply lines.
