E11, E12, F11, F12, G11, G12
AVSS
Analog Supply Ground Shield. Tie to AVSS at the DAC.
E13
IRQ/UNSIGNED
If PIN_MODE = 0, IRQ: Active low open-drain interrupt request
output, pull up to DVDD33 with 10 kΩ resistor.
If PIN_MODE = 1, UNSIGNED: Digital input pin where 0 = twos
complement input data format, 1 = unsigned.
E14
RESET/PD
If PIN_MODE = 0, RESET: 1 resets the AD9735.
If PIN_MODE = 1, PD: 1 puts the AD9735 in the power-down state.
