Negative Supply Voltage (0 V for single
supply operation).
Bipolar Offset Resistor. This provides
access to the on-chip application resistors
and allows different output voltage ranges.
Reference Output. The on-chip reference
is provided at this pin and is used when
configuring the part for bipolar outputs.
Analog Ground.
Data Bit 11. Most Significant Bit (MSB).
Digital Ground.
Data Bit 4 to Data Bit 1.
Data Bit 0. Least Significant Bit (LSB).
Chip Select Input (Active LOW). The
device is selected when this input is active.

Description
Write Input (Active LOW). This is used in
conjunction with CS to write data into the
input latch of the AD7245A.
Load DAC Input (Active LOW). This is
an asynchronous input which when active
transfers data from the input latch to the
DAC latch.
Clear Input (Active LOW). When this
input is active the contents of the DAC
latch are reset to all 0s.
Positive Supply Voltage.
Feedback Resistor. This allows access to
the amplifier’s feedback loop.
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.
