*
1 The pin 12 output amplitude should be set to V
O
. AV = 20log (V
O
/ V
IN
) [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 (H
OS
) 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.
