The INA823DR can handle input voltages up to ±650mV, but it's recommended to keep the input voltage within ±500mV to ensure accurate measurements.
The gain of the INA823DR is calculated by dividing the output voltage by the input voltage. The gain is typically set to 1, 2, 4, or 8 using the gain pins (G0 and G1).
The REF pin is used to set the reference voltage for the amplifier. It can be connected to a voltage reference or a resistive divider to set the output voltage range.
To reduce noise and interference, use proper PCB layout techniques, such as separating analog and digital grounds, using shielding, and adding bypass capacitors to the power supply.
The INA823DR has a bandwidth of 35kHz, making it suitable for low-frequency applications. For high-frequency applications, consider using a different amplifier with a higher bandwidth.
