A4, A5, A6, A9, A10, A11, B4, B5, B6, B9, B10, B11, C4, C5, C6, C9, C10, C11, D4, D5, D6, D9, D10, D11 AVSS Analog Supply Ground. A7, B7, C7, D7 IOUTB DAC Negative Output. 10 mA to 30 mA full-scale output current. A8, B8, C8, D8 IOUTA DAC Positive Output. 10 mA to 30 mA full-scale output current. A12, A13, B12, B13, C12, C13, D12, D13 AVDD33 3.3 V Analog Supply. A14 DNC Do Not Connect. B14 I120 Nominal 1.2 V Reference. Tie to analog ground via 10 kΩ resistor to generate a 120 μA reference current. C14 VREF Band Gap Voltage Reference I/O. Tie to analog ground via 1 nF capacitor; output impedance is approximately 5 kΩ. D1, E2, E3, E4, F2, F3, F4, G1, G2, G3, G4 CVSS Clock Supply Ground. D14 IPTAT Factory Test Pin. Output current, proportional to absolute temperature, is approximately 10 μA at 25°C with a slope of approximately 20 nA/°C. E1, F1 DACCLK−/DACCLK+ Negative/Positive DAC Clock Input (DACCLK). 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 AD9736. If PIN_MODE = 1, PD: 1 puts the AD9736 in the power-down state. F13 CSB/2× See the Serial Peripheral Interface section and the Pin Mode Operation section for pin description. F14 SDIO/FIFO See the Pin Mode Operation section for pin description. G13 SCLK/FSC0 See the Pin Mode Operation section for pin description. G14 SDO/FSC1 See the Pin Mode Operation section for pin description. H1, H2, H3, H4, H11, H12, H13, H14, J1, J2, J3, J4, J11, J12, J13, J14 DVDD18 1.8 V Digital Supply. |
