AF Conditions:
Input MUX signal is 1VP–P = 1kHz; VPILOT = 32mV (9%), oscillator adjusted to fOSC = 228kHz at VI = 0V,
unless otherwise specified. (All figures are measured with a roll–off network of 50kHz (2dB down at
38kHz) at the input.
AC Electrical Characteristics: (All parameters are measured in the circuit at nominal supply
voltage(VCC = 8.5V) and TA = +25°C)
