VII. High EL Brightness With Parallel D356A (Option 1)
Two or more D356A EL drivers may be operated in parallel to increase the brightness of the EL lamp by 50-100%.
In this circuit, an external clock signal with 50% duty cycle is needed to synchronously drive both D356A ICs. The
clock signal voltage should not exceed V+.

VIII. High EL Brightness With Parallel D356A (Option 2)
Two or more D356A EL drivers may be operated in parallel to increase the brightness of the EL lamp by 50-100%.
In this circuit, two D356A ICs are operating synchronously using their internal oscillators. The lamp frequency is
controlled by a shared CLF capacitor.
