AD7248A PIN FUNCT ION DE SCRIPT ION
(DIP PIN NUMBE RS)
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
DB11
Data Bit 11. Most Significant Bit (MSB).
6-11
DB10-DB5
Data Bit 10 to Data Bit 5.
12
DGND
Digital Ground.
13-16 DB4-DB1
Data Bit 4 to Data Bit 1.
17
DB0
Data Bit 0. Least Significant Bit (LSB).
18
CS
Chip Select Input (Active LOW). T he de-
vice is selected when this input is active.
Pin
Mnemonic
Description
19
WR
Write Input (Active LOW). T his is used in
conjunction with
CS
to write data into the
input latch of the AD7245A.
20
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.
21
CLR
Clear Input (Active LOW). When this in-
put is active the contents of the DAC latch
are reset to all 0s.
22
V
DD
Positive Supply Voltage.
23
R
FB
Feedback Resistor. T his allows access to
the amplifier’s feedback loop.
24
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.
