GND  
IO supply voltage. (1.7 V to 5.5 V). This pin sets the I/O operating voltage for the device.  
Ground reference point for all circuitry on the device.  
GND  
10, 36  
Serial interface data output. The SDO pin must be enabled before operation by setting the SDO-EN bit.  
Data are clocked out of the input shift register on either rising or falling edges of the SCLK pin as specified  
by the FSDO bit (rising edge by default).

Serial interface clock.  
Serial interface data input. Data are clocked into the input shift register on each falling edge of the SCLK  
pin.  
Active low serial data enable. This input is the frame synchronization signal for the serial data. When the  
signal goes low, it enables the serial interface input shift register.

Toggle pins. Control signals for those DAC outputs configured for toggle operation to switch between the  
two DAC data registers associated with each DAC. A logic low updates the DAC output to the value set by  
Register A. A logic high updates the DAC output to the value set by Register B. Connect the TOGGLE  
pins to ground if not using the toggle operation.  
Active low synchronization signal. When the LDAC pin is low, the DAC outputs of those channels  
configured in synchronous mode are updated simultaneously. Connect to VIO if unused.

Active low reset input. Logic low on this pin causes the device to issue a power-on-reset event.  
Active low clear input. Logic low on this pin clears all DAC outputs to their clear code. Connect to VIO if  
unused.  
ALMOUT is an open drain alarm output. An external 10-kpull-up resistor to a voltage no higher than VIO  
is required.

Output negative analog power supply (-21.5 V to 0 V).  
VSS  
Reference input to the device when operating with external reference. When using internal reference, this  
is the reference output voltage pin. Connect a 150-nF capacitor to ground.

Ground reference point for the internal reference.  
Analog supply voltage (4.5 V to 5.5 V). This pin must be at the same potential as the VDD pin.  
Digital supply voltage (4.5 V to 5.5 V). This pin must be at the same potential as the VAA pin.

THERMAL  
PAD  
The thermal pad is located on the package underside. The thermal pad should be connected to any  
internal PCB ground plane through multiple vias for good thermal performance.
