S9408
OVERVIEW
The S9408 DACPOT is a serial input, voltage output,
quad 8-bit digital to analog converter. The S9408 oper-
ates from a single +2.7V to +5.5V supply. Internal preci-
sion 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 associ-
ated circuits which include an enhanced unity-gain opera-
tional amplifier output, an 8-bit data latch, an 8-bit non-
volatile 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.
