Description
1 to 4
R1A, R2B,
R2_3B, R3A
DAC A 4-Quadrant Resistors. Allow a number of configuration modes, including bipolar operation with
minimum of external components.
5, 26
VREFA, VREFB
DAC Reference Voltage Input Terminals.
6
DGND
Digital Ground Pin.
7
LDAC
Load DAC Input. Allows asynchronous or synchronous updates to the DAC output. The DAC is
asynchronously updated when this signal goes low. Alternatively, if this line is held permanently low, an
automatic or synchronous update mode is selected whereby the DAC is updated on the rising edge of CS.
8
DAC A/B
Selects DAC A or B. Low selects DAC A, and high selects DAC B.
9, 34 to 37
NC
Not internally connected.
10 to 21
DB11 to DB0
Parallel Data Bits 11 through 0.
22
CS
Chip Select Input. Active low. Used in conjunction with R/W to load parallel data to the input latch or to
read data from the DAC register. Edge sensitive; when pulled high, the DAC data is latched.
23
R/W
Read/Write. When low, used in conjunction with CS to load parallel data. When high, used in conjunction
with CS to read back contents of DAC register.
24
CLR
Active Low Control Input. Clears DAC output and input and DAC registers.
25
VDD
Positive Power Supply Input. These parts can be operated from a supply of 2.5 V to 5.5 V.
27 to 30
R3B, R2_3B,
R2B, R1B
DAC B 4-Quadrant Resistors. Allow a number of configuration modes, including bipolar operation with a
minimum of external components.
31, 40
RFBB, RFBA
External Amplifier Output.
32
IOUT2B
DAC A Analog Ground. This pin typically should be tied to the analog ground of the system, but can be
biased to achieve single-supply operation.
33
IOUT1B
DAC B Current Outputs.
38
IOUT1A
DAC A Current Outputs.
39
IOUT2A
DAC A Analog Ground. This pin typically should be tied to the analog ground of the system, but can be
biased to achieve single-supply operation.
EPAD
Exposed pad must be connected to ground.
