DESCRIPTION
NO.
NAME
1
FB0
Input
Voltage feedback pin for channel 0.
In voltage-output mode, connect to OUT0 for closed-loop amplifier output.
In current-output mode, keep the FB0 pin unconnected to minimize leakage current.
2
OUT0
Output
Analog output voltage from DAC channel 0.
3

NC
No connection. Leave the pin unconnected.
4

NC
No connection. Leave the pin unconnected.
5
GPIO/SDO
Input/Output
General-purpose input/output configurable as LDAC, PD, PROTECT, RESET, SDO, and STATUS.
For STATUS and SDO, connect the pin to the IO voltage with an external pullup resistor.
If unused, connect the GPIO pin to VDD or AGND using an external resistor. This pin can ramp up before VDD.
6
SCL/SYNC
Output
I2C serial interface clock or SPI chip select input. This pin must be connected to the IO voltage using an external
pullup resistor. This pin can ramp up before VDD.
7
A0/SDI
Input
Address configuration pin for I2C or serial data input for SPI.
For A0, connect this pin to VDD, AGND, SDA, or SCL for address configuration (Section 7.5.2.2.1).
For SDI, this pin does not need to be pulled up or pulled down. This pin can ramp up before VDD.
8
SDA/SCLK
Input/Output
Bidirectional I2C serial data bus or SPI clock input. This pin must be connected to the IO voltage using an external
pullup resistor in I2C mode. This pin can ramp up before VDD.
9
NC
NC
No connection. Leave the pin unconnected.
10
NC
NC
No connection. Leave the pin unconnected.
11
OUT1
Output
Analog output voltage from DAC channel 1.
12
FB1
Input
Voltage feedback pin for channel 1.
In voltage-output mode, connect to OUT1 for closed-loop amplifier output.
In current-output mode, keep the FB1 pin unconnected to minimize leakage current.
13
CAP
Power
External bypass capacitor for the internal LDO. Connect a capacitor (approximately 1.5 μF) between CAP and AGND.
14
AGND
Ground
Ground reference point for all circuitry on the device.
15
VDD
Power
Supply voltage.
16
VREF
Power
External reference input. Connect a capacitor (approximately 0.1 μF) between VREF and AGND.
Use a pullup resistor to VDD when the external reference is not used. This pin must not ramp up before VDD. In case
an external reference is used, make sure the reference ramps up after VDD.
