NO.  
When using internal reference, this is the reference output voltage pin (default). When using an  
external reference, this is the reference input pin to the device.

amplifier gain for all four channels is set to 1. When tied to VIO the initial buffer amplifier gain is 2.  
Changing the state of this pin after power-up does not affect the device operation.  
Reset select pin. When tied to GND all four DACs reset to zero scale. When connected to VIO all four  
DACs reset to midscale.  
RSTSEL  
REFDIV  
LDAC  
Sets the reference divider configuration after a power-up or reset event. When tied to GND, the  
reference voltage is not divided down. When tied to VIO the reference voltage is divided by 2. Changing  
the state of this pin after power-up does not affect the device operation.

A high-to-low transition on the LDAC pin causes the DAC outputs of those channels configured in  
synchronous mode to update simultaneously. The pin can be tied permanently to GND.  
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.

SCLK

Serial interface clock.  
Serial interface data input. Data are clocked into the input shift register on each falling edge of the  
SCLK pin.  
Serial interface data output (default). The SDO pin is in high impedance when CS pin is high. 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. Alternatively the pin can be configured as an ALARM open-drain output to indicate a  
CRC or reference alarm event. If configured as ALARM a 10 kΩ, pull-up resistor to VIO is required.
