Notes:

1. Im is the maximum peak current for which the output voltage specifications are guaranteed, however the If RMS rating must not be exceeded.

2. All specifications measured at 25°C, Rl=10 kΩ, unless otherwise noted.

3. It is recommended to add a 1

μF capacitor connected between the common terminal 4 and the +12 V terminal 1 to avoid noise problems.
