IOVDD
P
This is the digital I/O supply pin. This supply is separated from the
digital core supply of AS7058 and can for example be connected to
a 1.2 V supply voltage to enable lower I²C or SPI interface voltages
to eliminate the need of external level shifters.
E6
DVDD
P
Positive digital supply terminal of AS7058 which needs to be
connected to a 1.8 V power supply.
F1
AVDD2
P
Positive analog supply terminal 2 which supplies all analog blocks of
the device. Needs to be connected to a low noise 1.8V power
supply.
