INA188ID Frequently Asked Questions (FAQ)

  • The INA188ID can handle input voltages up to ±650mV, but it's recommended to keep the input voltage within ±500mV to ensure accurate measurements.

  • The gain resistor (Rg) value depends on the desired gain and the input voltage range. A higher Rg value results in higher gain, but also increases noise sensitivity. TI provides a gain calculator tool to help with Rg selection.

  • The REF pin is the reference voltage input for the INA188ID. Connect it to a stable voltage source (e.g., a voltage regulator output) or to the analog ground (AGND) if the reference voltage is not used.

  • To ensure accurate measurements in high-temperature environments, use a thermally stable gain resistor (Rg) and ensure good thermal coupling between the INA188ID and the surrounding PCB. Also, consider using a temperature-compensated voltage reference for the REF pin.

  • Keep the INA188ID and its associated components (e.g., Rg, input resistors) close together to minimize noise. Use a star-grounding scheme, and route the input signals away from noisy digital signals. Also, use a solid ground plane and decouple the power supply lines.
