PIN TYPE DESCRIPTION
NO. NAME
1 OUT0 Output DAC output channel 0
2 AVDD Power Analog power supply
3 SCL/CS Input I2C: Clock input. SPI: Active-low serial data enable. This input is the frame synchronization signal for the serial data. When the signal goes low, this pin enables the serial interface input shift register.
4 SDA/SCLK Input/Output I2C: Bidirectional data line SPI: Clock input
5 A0/SDI Input I2C: Target address selector SPI: Data input. Data are clocked into the input shift register on each falling edge of the SCLK pin.
6 FLEXIO Input/Output FLEXIO pin, including GPIO and CLEAR pin functionality
7 OUT8 Output DAC output channel 8
8 OUT9 Output DAC output channel 9
9 OUT10 Output DAC output channel 10
10 OUT11 Output DAC output channel 11
11 OUT12 Output DAC output channel 12
12 OUT13 Output DAC output channel 13
13 OUT14 Output DAC output channel 14
14 OUT15 Output DAC output channel 15
15 GND Power Ground reference point for all circuitry on the device
16 GND Power Ground reference point for all circuitry on the device
17 LDAC Input Active-low DAC synchronization signal. A high-to-low transition on the LDAC pin simultaneously updates the outputs configured in synchronous mode
18 VIO Power IO supply voltage. This pin sets the I/O operating voltage for the device.
19 A1/SDO Input/Output I2C: Target address selector. SPI: Data output. 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.
20 RESET Input Active low reset input, logic low on this pin causes the device to initiate a reset event
21 REF Input/Output DAC voltage reference input/output. This pin acts as input pin REFIN by default (with internal reference disabled). If internal reference is enabled, this pin acts as output pin REFOUT.
22 OUT7 Output DAC output channel 7
23 OUT6 Output DAC output channel 6
24 OUT5 Output DAC output channel 5
25 OUT4 Output DAC output channel 4
26 OUT3 Output DAC output channel 3
27 OUT2 Output DAC output channel 2
28 OUT1 Output DAC output channel 1
