Typical values are typical under the recommended operation conditions.
Maximum values are maximum values
under the recommended operation conditions.
However, the input pin’s high-level voltage value is VDD33 and the low-level input voltage value is VSS.
[Note 2]
This depends on the sampling frequency and firmware.
The firmware used in this case requires a processing
load of approximately 150 MHz at a sampling frequency of 48 kHz.

However, the input pin’s high-level voltage value is VDD33 and the low-level input voltage value is VSS.
[Note 2]
The current consumption increases at higher temperatures.
