Other Parts Discussed in Thread: DAC8718
Hi Team,
Please see below circuit of DAC output, this circuit is working fine,
Please see the net name of VOUT_1...3, If unfortunately, I apply the +24V input on these output pins means circuit/ OPA1664 op-amp get damaged.
For that, we provided the 80mA restartable fuse at the end of output voltage and another end of the fuse terminal connected to +24V input voltage. At that time, we observed the OPA1664 part is getting more heat.
Please suggest to me the circuit to protect, if the +24 VDC input on that DAC output( VOUT_1...3)
And Whether we applied the fuse on output is the correct methodology. Please suggest on this also.
Best Regards,
Dinesh KS.
