ADS7138: Whether the ADS7138 has an interrupt function

Part Number: ADS7138

Whether the ADS7138 has an interrupt function. The customer wanted to use an ADC to collect 5V for monitoring. 12-bit, IIC interface, no rate required, whether 7138 can be used. Or is there any other recommendation

Hi aiwen,

The ADS7138 has an 'Alert' output which could be used as an interrupt to the controller. It has programmable thresholds as well as some built in noise filtering capabilities.

Hi tom；

I am very appreciate to receive your response，I would like to check again whether it can be used to collect 5V voltage？Thanks!

The ADS7138 uses AVdd for its reference. With a 5.1 to 5.5V supply, you can monitor a 5V input. With a 5.0V supply, you could use a voltage divider on the 5V source that you plan to monitor.
