I'm reading the datasheet of
and I'm not sure how to configure the supply rails. The video input signals are AC coupled, hence they span below the GND rail.
I don't want to put a common mode voltage because I have very small free space on the board. At page 11 I read:
Vcc: Positive power supply
Vee: Negative Power Supply. Ground for single-supply operation.
I wonder if I can generate a -3V rail with an
LTC1983-3 (http://cds.linear.com/docs/en/datasheet/1983fc.pdf) and then power the
MAX4310 using a +5V on Vcc and -3V on Vee.
It hasn't a ground pin, though... how it can sense "where" is the 0V rail?
