Part Number: ADS7142

Hi Team,

In an implementation, without using the ALERT and BUSY/RDY pins, should these pins be connected high, low, or NC?

Thanks,

Matt

Hi Matt,

BUSY/RDY is a push-pull output and can be left floating. ALERT is also an output, but is open-drain so while it can also be left floating, it's probably better to weakly pull it up to VCC, consider a 50-100kOhm.
