Electrical Characteristics Test Method
ICC1 Circuit Current1
Measuring conditions are as listed in supplementary Table.
Measured with a current meter at test point IA.
ICC2 Circuit Current2
Measuring conditions are as listed in supplementar
Measured with a current meter at test point IB.
Vomax Output Dynamic Range
Decrease V30 gradually, and measueform output is distorted. The voltage is called VOL.
Next, increase V30 gradually, an the top of waveform output is distorted. The voltage is
called VOH.
Voltage Vomax is calcul:
Vomax = VOH − V

Application Method for M52742ASP
Clamp Pulse Input
Clamp pulse width is recommended
above 15 kHz, 1.0 µs
above 30 kHz, 0.5 µs
above 64 kHz, 0.3 µs.
The clamp pulse circuit in ordinary set is a long round about way, and beside high voltage, sometimes connected to
external terminal, it is very easy affected by large surge.
Therefore, the figure shown right is recommended.
