[7] Parallel synchronous operation of multiple ICs

Multiple instances of this IC can be operated in parallel. If the OSC terminals (pin 1) and Off terminals (pin 15) are

connected to each other as shown in figure 7, the ICs will operate at the same frequency.

It is possible to operate this IC (the AN8018SA) with the two-channel totem pole output IC AN8017SA in parallel

synchronous mode.

1. Usage notes

1) The parallel synchronous operation with the single-channel AN8016SH/AN8016NSH is not possible.

2) The remote on/off with the single IC itself is not possible. Only the simultaneous remote on/off of all ICs is

possible.
