B14

I120

Nominal 1.2V reference tied to analog ground via 10kohm resistor to generate a

120uA reference current

C14

VREF

Bandgap voltage reference I/O, tie to analog ground via 1nF capacitor, output

impedance approximately 5kohms

D1, E2, E3, E4, F2, F3, F4, G1, G2, G3, G4

VSSC

Clock supply ground

D14

IPTAT

Factory test, output current proportional to absolute temperature, approximately

10uA at 25C with approximately 20nA/C slope

E1, F1

CLK-, CLK+

Negative, Positive DAC clock input (DACCLK)

E11, E12, F11, F12, G11, G12

VSSA

Analog supply ground shield

E13

IRQ / UNSIGNED

If PIN_MODE = 0, IRQ: Active low open-drain interrupt request output, pull up to

VDD3.3 with 10kohm resistor

If PIN_MODE = 1, UNSIGNED: Digital input pin where 0 = two’s complement input

data format, 1 = unsigned

E14

RESET / PD

If PIN_MODE = 0, RESET: 1 resets the AD9736

If PIN_MODE = 1, PD: 1 puts the AD9736 in the power down state
