PIN FUNCTION DESCRIPTIONS
Pin
No.
Mnemonic Function
1-8
D7–D0
Parallel Data Inputs. Eight-bit data is loaded to the input register of the AD7302 under the control of
CS
and
WR.
9
CS
Chip Select. Active low logic input.
10
WR
Write Input.
WR is an active low logic input used in conjunction with CS and A/B to write data to the selected
DAC register.
11
A/B
DAC Select. Address pin used to select writing to either DAC A or DAC B.
12
PD
Active low input used to put the part into low power mode reducing current consumption to less than 1
A.
13
LDAC
Load DAC Logic Input. When this logic input is taken low both DAC outputs are simultaneously updated with
the contents of their DAC registers. If
LDAC is permanently tied low, the DACs are updated on the rising
edge of
WR.
14
CLR
Asynchronous Clear Input (Active Low). When this input is taken low the DAC registers are loaded with all
zeroes and the DAC outputs are cleared to zero volts.
15
VDD
Power Supply Input. These parts can be operated from 2.7 V to 5.5 V and should be decoupled to AGND.
16
REFIN
External Reference Input. This can used as the reference for both DACs. The range on this reference input is
1 V to VDD/2. If REFIN is directly tied to VDD the internal VDD/2 reference is selected.
17
AGND
Analog Ground reference point and return point for all analog current on the part.
18
VOUTB
Analog output voltage from DAC B. The output amplifier can swing rail to rail on its output.
19
VOUTA
Analog output voltage from DAC A. The output amplifier can swing rail to rail on its output.
20
DGND
Digital Ground reference point and return point for all digital current on the part.
