Hello!

I have question regarding the analog channels of the AD7770: are the analog channels isolated in AD7770? Can they be coupled directly with signals coming from plcs? Isolation amplifiers required for AD7770 if necessary?

Thank you!

Hi,

What type of application do you have? The AD7770 has no isolator included, an isolation can be added before the ADC. Please take note that the AD7770 input voltage range should not go beyond AVss-0.3V to AVdd+0.3V or 3.96V. Subjecting the AD7770 beyond the specified input voltage will damage it .

Regards,

Jonathan
