Note 1. Measured using a 1 MHz sinusoid, 20 V peak to peak, line to line at point “AT” (Guaranteed but not tested).

Note 2. Measured using a 1 MHz sinusoid, 860 mV peak to peak, line to line at point “AT” (100% tested).

Note 3. Measured using a 1 MHz sinusoid, 860 mV peak to peak, line to line at point “AT”. Measured from input zero crossing point.
