## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSS | power_in | Negative Analog Supply Voltage: −12 V ± 5% to −15 V ± 10% for specified performance. |
| 2 | VDD | power_in | Positive Analog Supply Voltage: 12 V ± 5% to 15 V ± 10% for specified performance. |
| 3 | CLR | input | Level-sensitive, active-low input; a falling edge of CLR resets VOUT to AGND while the register contents are untouched. |
| 4 | LDAC | input | Active-low control input that transfers the input register contents to the DAC register, and can be tied permanently low so outputs update on the rising edge of SYNC. |
| 5 | SYNC | input | Active-low frame synchronization input; when it goes low it powers on the SCLK and SDIN buffers and enables the input shift register, with data clocked in on the falling edges of the following 16 clocks. |
| 6 | SCLK | input | Serial clock input; data is clocked into the input register on its falling edge, at transfer rates of up to 8 MHz. |
| 7 | SDIN | input | Serial data input; data is clocked into the 16-bit register on the falling edge of the serial clock. |
| 8 | SDO | output | Open-drain serial data output for daisy-chaining or shift-register readback; it must be pulled to logic high with an external pull-up resistor of ~5 kΩ. |
| 9 | DGND | power_in | Digital ground, the reference for all digital circuitry. |
| 10 | PD | input | Active-low control input that puts the DAC into a power-down state. |
| 11 | AGND | power_in | Analog ground, the reference for all analog circuitry. |
| 12 | AGNDS | power_in | Analog ground sense; normally tied to AGND. |
| 13 | VOUT | output | Analog output voltage of the DAC, buffered and specified up to ±14 V output range. |
| 14 | REFGND | power_in | Reference ground; tie this pin to 0 V. |
| 15 | REFIN | input | Voltage reference input, internally buffered before being applied to the DAC; for the bipolar ±10 V output range REFIN is 5 V. |
| 16 | REFGND | power_in | Reference ground; tie this pin to 0 V. |
