*1 The pin 12 output amplitude should be set to VO. AV = 20log (VO / VIN) [dB]
*2 For the method by which the output waveform is determined, refer to Fig. 14.
*3 An input frequency should be measured that produces a level of -1dB for a high output level (HOS) for the sawtooth waveform at an input frequency of
30kHz.
*4 The temperature is measured at the point where the temperature is raised to above Ta = 75˚C and the output level of pin 9 is high.
