The ICL7135CN can handle input voltages up to 40V, but it's recommended to keep it below 30V for reliable operation.
To ensure accurate voltage measurement, make sure to use a high-impedance input source, keep the input voltage within the recommended range, and use a low-noise power supply. Also, consider using a voltage reference IC like the TL431 to improve accuracy.
No, the ICL7135CN is not designed for high-current applications. It's intended for low-power, low-current applications such as voltage monitoring and measurement. If you need to handle high currents, consider using a different IC or adding external current-limiting components.
Calibration involves adjusting the internal voltage reference and gain settings. Refer to the datasheet for the calibration procedure, which involves applying a known input voltage and adjusting the internal reference voltage to match the expected output voltage.
The typical settling time for the ICL7135CN is around 10-15 microseconds, but this can vary depending on the input voltage, output load, and other factors. Consult the datasheet for more information on settling time and response characteristics.
