PCM1864　Analog input detection

Hello, Hasebe-san,

Regarding the analog input protection for the PCM1864, there's no detection function at the input terminal as you mentioned. We only recommend to be between the absolute maximum ratings and avoid to be at the limits. It may cause permanent damage to the device. This range is from -1.7V to 5.0V at analog inputs.

Actually, the ADC monitors the input signal level while in active mode. The energysense will send an interrupt if the input level is below a configured threshold. It is only used to verify if the analog signal is significant to place the device in sleep or active mode.

Hello Luis-san,

Thank you for your quick reply.

I understand your comments.

I have one more question.
I am using gui of ppc2.
I found the function of signal loss detect .
Then it's setting range(unit) is "min".
If this function is not possible to set in seconds?

Best Regards,

Hello, Hasebe-san,

As described in datasheet, Signal Detect Loss Time only can be configured from 1 minute to 5 minutes. So, it is not possible to set it in seconds.
