Description
Chip Select Input for MS Nibble. (Active
LOW). This selects the upper 4 bits of the
input latch. Input data is right justified.
Chip Select Input for LS byte. (Active
LOW). This selects the lower 8 bits of the
input latch.
Write Input. This is used in conjunction
with CSMSB and CSLSB to load data
into the input latch of the AD7248A.
Load DAC Input (Active LOW). This is
an asynchronous input which when active
transfers data from the input latch to the
DAC latch.
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
0 V to +10 V or –5 V to +5 V.
