FEATURES…
The SP7516 and HS3160 are precision 16-bit multi-
plying DACs. The DACs are implemented as a one-
chip CMOS circuit with a resistor ladder network.
Three output lines are provided on the DACs to allow
unipolar and bipolar output connection with a mini-
mum of external components. The feedback resistor
is internal. The resistor ladder network termination is
externally available, thus eliminating an external re-
sistor for the 1 LSB offset in bipolar mode.
The SP7516 is available for use in commercial and
industrial temperature ranges, packaged in a 24-pin
SOIC. The HS3160 is available in commercial
and military temperature ranges, packaged in a
24–pin side–brazed DIP. For product processed
and screened to the requirements of MIL–M–
38510 and MIL–STD–883C, please consult the
factory (HS3160B only).
PRINCIPLES OF OPERATION
The SP7516/HS3160 achieve high accuracy by using
a decoded or segmented DAC scheme to implement
this function. The following is a brief description of
this approach.
