OVERVIEW
The
S9408 DACPOT is a
serial input, voltage
output, quad 8-bit
digital to analog
converter. The S9408
operates from a single
+2.7V to +5.5V supply.
Internal precision
buffers swing
rail-to-rail and the
reference input range
includes both ground and
the positive supply.
The S9408 integrates
four 8-bit DACs and
their associated
circuits which include
an enhanced unity-gain
operational amplifier
output, an 8-bit data
latch, an 8-bit
nonvolatile register,
and an industry-standard
serial interface for
reading and writing data
to the DACs' data
latches and registers.
The DACs are
independently
programmable and each
has its own electrically
isolated Vreference
inputs.
