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 in-
put 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.
