Description
15
1
B2
LDAC
Pulsing this pin low allows any or all DAC registers to be updated if the input registers
have new data. This allows all DAC outputs to simultaneously update. Alternatively,
this pin can be tied permanently low.
16
2
A4
A0
Address Input. Sets the least significant bit of the 7-bit slave address.
1
3
B3
VDD
Power Supply Input. These parts can be operated from 2.7 V to 5.5 V. Decouple the
supply with a 10 F capacitor in parallel with a 0.1 F capacitor to GND.
2
4
B4
VOUTA
Analog Output Voltage from DAC A. The output amplifier has rail-to-rail operation.
3
5
C4
VOUTC
Analog Output Voltage from DAC C. The output amplifier has rail-to-rail operation.
4
6
C3
VOUTE
Analog Output Voltage from DAC E. The output amplifier has rail-to-rail operation.
5
7
D4
VOUTG
Analog Output Voltage from DAC G. The output amplifier has rail-to-rail operation.

D3
VREFIN/VREFOUT
The AD5629R/AD5669R have a common pin for reference input and reference
output. When using the internal reference, this is the reference output pin. When
using an external reference, this is the reference input pin. The default for this pin is
as a reference input.
7
9
D2
CLR
Asynchronous Clear Input. The CLR input is falling edge sensitive. When CLR is low, all
LDAC pulses are ignored. When CLR is activated, the input register and the DAC
register are updated with the data contained in the CLR code register—zero scale,
midscale, or full scale. The default setting clears the output to 0 V.
8
10
D1
VOUTH
Analog Output Voltage from DAC H. The output amplifier has rail-to-rail operation.
9
11
C1
VOUTF
Analog Output Voltage from DAC F. The output amplifier has rail-to-rail operation.
10
12
C2
VOUTD
Analog Output Voltage from DAC D. The output amplifier has rail-to-rail operation.
11
13
B1
VOUTB
Analog Output Voltage from DAC B. The output amplifier has rail-to-rail operation.
12
14
A1
GND
Ground Reference Point for All Circuitry on the Parts.
13
15
A3
SDA
Serial Data Input. This is used in conjunction with the SCL line to clock data into or
out of the 32-bit input shift register. It is a bidirectional, open-drain data line that
should be pulled to the supply with an external pull-up resistor.
14
16
A2
SCL
Serial Clock Line. This is used in conjunction with the SDA line to clock data into or
out of the 32-bit input shift register.
17
N/A
Exposed Pad
(EPAD)
The exposed pad must be tied to GND.
