AD7245A PIN FUNCTION DESCRIPTIONS
(DIP PIN NUMBERS)
Pin
Mnemonic Description
lVSS
Negative Supply Voltage (0 V for single
supply operation).
2ROFS
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
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). The
device is selected when this input is active.
Pin
Mnemonic
Description
19
WR
Write Input (Active LOW). This is used in
conjunction with
CS to write data into the
input latch of the AD7245A.
20
LDAC
Load DAC Input (Active LOW). This 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
input is active the contents of the DAC
latch are reset to all 0s.
22
VDD
Positive Supply Voltage.
23
RFB
Feedback Resistor. This allows access to
the amplifier’s feedback loop.
24
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.
