I have some questions about ADXL362 from my customer.
The datasheet says as following.
Operating Voltage Range (VS) 1.6 2.0 3.5 V
I/O Voltage Range (VDD I/O) 1.6 2.0 VS V
Please find attached file.
In this case, Vs may be a little bit lower than VDDIO by the filter.
How much volts can VDDIO bear higher than Vs ? Or can the circuit like this be not permitted ?
And if possible, please let me know the reason why Vs should be higher than VDDIO.
The datasheet says,"it must always be started up from 0 V".
Please let me know the reason why it must always be started up from 0 V.
If we cannnot reduce supply voltage to 0V at starting up, how much volts can this device be started up from ?
