I am using in portable ultrasound design.
I am using 8 of AFE5809 chips to get more channel options .My main concern is In the TGC section producing VCNTL signals.(VCNTL_IN_P/VCNTL_IN_N)
This signal is an analog signal that controls the attenuator in the RX AFEs. In the most typical case it provides a ramp voltage to the RX AFE. what voltage range VCNTL signal should be used ?
Can I use 0V to +1.5V or it should be always be 10v and -10 v that is mentioned in datasheet .
See attached design for your review.
