Dual, Serial Input 16-Bit Multiplying Digital-to-Analog Converter
is
a
dual,
16-bit,
current-output
The applied external reference input voltage V
determines the full-scale output current. An internal
feedback resistor (R
FB
) provides temperature tracking
for the full-scale output when combined with an
external I-to-V precision amplifier.
A
high-speed,
compatible inputs using serial data in (SDI), clock
(CLK),
and
a
chip-select
level-sensitive load DAC strobe (LDAC) input allows
simultaneous
update
of
previously loaded input registers. Additionally, an
internal power-on reset forces the output voltage to
zero at system turn-on. An MSB pin allows system
reset assertion (RS) to force all registers to zero code
when MSB = 0, or to half-scale code when MSB = 1.
