¹All ac, Hz, and duty cycle are specified from 1% to 100% of range. Inputs below 1% of range are not specified. ²Typically, open circuit test voltage is 2.0 V and short circuit current is <0.6 mA. ³Specifications do not include errors due to test lead capacitance and capacitance floor (may be up to 1.5 nF in the 40 nF range). ⁴Typical means when the frequency is at 50 Hz or 60 Hz and the duty cycle is between 10% and 90%.
