AD7248A PIN FUNCTION DESCRIPTIONS
(ANY PACKAGE)
Pin
Mnemonic
Description
l
VSS
Negative Supply Voltage (0 V for single
supply operation).
2
ROFS
Bipolar Offset Resistor. This provides
access to the on-chip application resistors
and allows different output voltage ranges.
3
REF OUT
Reference Output. The 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). This selects the upper 4 bits of the
input latch. Input data is right justified.
15
CSLSB
Chip Select Input for LS byte. (Active
LOW). This selects the lower 8 bits of the
input latch.
16
WR
Write Input. This 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). This is
an asynchronous input which when active
transfers data from the input latch to the
DAC latch.
18
VDD
Positive Supply Voltage.
19
RFB
Feedback Resistor. This allows access to
the amplifier’s feedback loop.
20
VOUT
Output Voltage. Three different output
voltage ranges can be chosen: 0 V to
5 V,
0 V to 10 V or –5 V to +5 V.
