PRODUCTION DATA
PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
AGND | 2, 35, 38, 40, 42, 43, 46, 47 | Analog ground | Connect to 0 V. |
AGND-OUT | 8 | Analog ground | Connect to 0 V. Measure DAC output voltage with respect to this node. |
AGND-TnH | 14 | Analog ground | Connect to 0 V. Integrated deglitcher clock ground. |
ALARM | 19 | Output | Alarm output |
AVDD | 39, 41 | Power | Positive low voltage analog power supply |
CLR | 30 | Input | DAC registers clear pin, active low |
DGND | 16, 17, 20, 21, 22, 23, 26 | Digital ground | Connect to 0 V. |
DVDD | 27 | Power | Digital power supply pin |
RFB | 9 | Input | Integrated precision resistor feedback node |
IOVDD | 28 | Power | Interface power supply pin |
LDAC | 18 | Input | Load DAC pin, active low |
NC | 1, 12, 13, 15, 24, 25, 29, 36, 37, 48 | — | No connection, leave floating |
OUT | 7 | Output | Unbuffered voltage output |
RCM | 11 | Input | Integrated precision resistor common-mode node |
REFNF | 5 | Input | External negative reference input. Connect to 0 V for unipolar DAC output. |
REFNS | 6 | Input | External negative reference sense node |
REFPF | 3 | Input | External positive reference input |
REFPS | 4 | Input | External positive reference sense node |
ROFS | 10 | Input | Integrated precision resistor offset node |
SCLK | 31 | Input | Serial clock input of serial peripheral interface (SPI).
Schmitt-trigger logic input. Data are transferred at rates of up to 50 MHz. |
SDIN | 32 | Input | Serial data input. Schmitt-trigger logic input. Data are clocked into the input shift register on the falling edge of the serial clock input. |
SDO | 34 | Output | Serial data output. Data are valid on the falling edge of SCLK. |
SYNC | 33 | Input | SPI bus chip select input (active low). Data bits are not clocked into the serial shift register unless SYNC is low. When SYNC is high, the SDO pin is in high-impedance status. |
VCC | 45 | Power | Analog positive power supply |
VSS | 44 | Power | Analog negative power supply |
