Mnemonic
Function
1
35
VREFGH
Reference Input for DACs G and H.
2
36
VREFEF
Reference Input for DACs E and F.
3
37
VREFCD
Reference Input for DACs C and D.
4
38, 39
VDD
Power Supply Pin(s). This part can operate from 2.5 V to 5.5 V, and the supply should be decoupled
with a 10 F capacitor in parallel with a 0.1 F capacitor to GND. Both VDD pins on the LFCSP package
must be at the same potential.
5
40
VREFAB
Reference Input for DACs A and B.
6–9,
11–14
1–4,
7–10
VOUTX
Output of DAC X. Buffered output with rail-to-rail operation.
10
5, 6
AGND
Analog Ground. Ground reference for analog circuitry.
15, 21–22
11,
17–18
DGND
Digital Ground. Ground reference for digital circuitry.
16
12
BUF
Buffer Control Pin. Controls whether the reference input to the DAC is buffered or unbuffered.
17
13
LDAC
Active Low Control Input. Updates the DAC registers with the contents of the input registers, which
allows all DAC outputs to be simultaneously updated.
18
14
A0
LSB Address Pin. Selects which DAC is to be written to.
19
15
A1
Address Pin. Selects which DAC is to be written to.
20
16
A2
MSB Address Pin. Selects which DAC is to be written to.
23–32
19–28
DB0–DB9
Ten Parallel Data Inputs. DB9 Is the MSB of these ten bits.
33
29
CS
Active Low Chip Select Input. Used in conjunction with WR to write data to the parallel interface, or
with RD to read back data from a DAC.
34
30
RD
Active Low Read Input. Used in conjunction with CS to read data back from the internal DACs.
35
31
WR
Active Low Write Input. Used in conjunction with CS to write data to the parallel interface.
36
32
GAIN
Gain Control Pin. Controls whether the output range from the DAC is 0 V to VREF or 0 V to 2 × VREF.
37
33
CLR
Asynchronous Active Low Control Input. Clears all input registers and DAC registers to zeros.
38
34
PD
Power-Down Pin. This active low control pin puts all DACs into power-down mode.
