NAME
FUNCTION
1, 2
—
GPIOA0, GPIOA1
General-Purpose I/O A0, A1. GPIOA0, A1 can sink and source 15mA.
3
4
EOC
Active-Low End-of-Conversion Output. Data is valid after the falling edge
of EOC.
4
7
DVDD
Digital Positive-Power Input. Bypass DVDD to DGND with a 0.1F
capacitor.
5
8
DGND
Digital Ground. Connect DGND to AGND.
6
9
DOUT
Serial-Data Output. Data is clocked out on the falling edge of the SCLK
clock in modes 00, 01, and 10. Data is clocked out on the rising edge of
the SCLK clock in mode 11. It is high impedance when CS is high.
7
10
SCLK
Serial-Clock Input. Clocks data in and out of the serial interface. (Duty
cycle must be 40% to 60%.) See Table 5 for details on programming the
clock mode.
8
11
DIN
Serial-Data Input. DIN data is latched into the serial interface on the
falling edge of SCLK.
9–12, 16–19
12–15,
22–25
OUT0–OUT7
DAC Outputs
13
18
AVDD
Positive Analog Power Input. Bypass AVDD to AGND with a 0.1F
capacitor.
14
19
AGND
Analog Ground
15, 23, 32, 33
—
N.C.
No Connection. Not internally connected.
20
26
LDAC
Active-Low Load DAC. LDAC is an asynchronous active-low input that
updates the DAC outputs. Drive LDAC low to make the DAC registers
transparent.
21
27
CS
Active-Low Chip-Select Input. When CS is low, the serial interface is
enabled. When CS is high, DOUT is high impedance.
22
28
RES_SEL
Reset Select. Select DAC wake-up mode. Set RES_SEL low to wake up
the DAC outputs with a 100k
resistor to AGND or set RES_SEL high to
wake up the DAC outputs with a 100k
resistor to VREF. Set RES_SEL
high to power up the DAC input register to FFFh. Set RES_SEL low to
power up the DAC input register to 000h.

GPIOC0, GPIOC1
General-Purpose I/O C0, C1. GPIOC0, C1 can sink 4mA and source 2mA.
