Hello all,

Two exact situations to be precise:

1. PIC is used to produce voltage level by means of PWM.
So, one pin configured as out is connected to an in-pin of an op-amp
arranged as an active low-pass filter. The op_amp (AD711 in this case) is
powered from +/-15V rails.

2.  8 out-pins of a PIC are connected to digital inputs of  a DAC (AD7524).
The DAC is powered from +15V.

The question in both cases: Is it OK (= safe for the PIC)? If not, how
should I arrange these connections?

Thanks.

Arkady
