WebThe most common is to use Schottky diodes (BAT54 series) to clamp the output of the amplifier to the range of the ADC. See Figure 2 and Figure … WebThe clamp voltage of this diode is 12.6V under a 40-V fault condition with a 1-kΩcurrent-limiting resistor. The 12.6-V clamp voltage is below the ADS8588S absolute maximum input voltage of ±15V, so it is effective at protecting the ADC. An optional TVS diode that can be used for the ADS8688 and ADS8681 devices is the CDSOD323-T12C diode.
