(ANY PACKAGE )
Pin
Mnemonic
Description
l
V
SS
Negative Supply Voltage (0 V for single
supply operation).
2
R
OFS
Bipolar Offset Resistor. T his provides
access to the on-chip application resistors
and allows different output voltage ranges.
3
REF OUT
Reference Output. T he on-chip reference
is provided at this pin and is used when
configuring the part for bipolar outputs.
4
AGND
Analog Ground.
5
DB7
Data Bit 7.
6
DB6
Data Bit 6.
7
DB5
Data Bit 5.
8
DB4
Data Bit 4.
9
DB3
Data Bit 3.
10
DGND
Digital Ground.
11
DB2
Data Bit 2/Data Bit 10.
12
DB1
Data Bit 1/Data Bit 9.
13
DB0
Data Bit 0 (LSB)/Data Bit 8.
Pin
Mnemonic
Description
14
CSMSB
Chip Select Input for MS Nibble. (Active
LOW). T his selects the upper 4 bits of the
input latch. Input data is right justified.
15
CSLSB
Chip Select Input for LS byte. (Active
LOW). T his selects the lower 8 bits of the
input latch.
16
WR
Write Input. T his is used in conjunction
with
CSMSB
and
CSLSB
to load data
into the input latch of the AD7248A.
17
LDAC
Load DAC Input (Active LOW). T his is
an asynchronous input which when active
transfers data from the input latch to the
DAC latch.
18
V
DD
Positive Supply Voltage.
19
R
FB
Feedback Resistor. T his allows access to
the amplifier’s feedback loop.
20
V
OUT
Output Voltage. T hree different output
voltage ranges can be chosen: 0 V to
+5
V,
0 V to +10 V or –5 V to +5 V.
