Hi, there
I am using the AD8364 power detector IC for my application. The IC has two separate channels. I am only using one of the channels, channel A. I have laid it out on my own PCB.
I'm having issues with the IC. Basically, the IC seems to be shorted: it's pulling a lot of current from the power supply, and when I limit the current to, say 150mA, the voltage supplied drops to 2v.
I followed advice from a previous post by doing the following:
- Decoupled pin DECB left floating.
- Offset comp capacitor pin CHPB left floating.
- Averaging capacitor pin CLPB left floating.
- Output pin OUTB left floating.
However, in my layout, pins INHB, INLB and VPSB are GROUNDED. My questions is whether this would lead to the issues I'm experiencing?
Thank you!
