DACs with Parallel I/O
The LTC2751 is a family of 12-, 14-, and 16-bit multi-
plying parallel-input, current-output DACs. They operate
from a single 2.7V to 5.5V supply. All parts are guaranteed
monotonic over temperature. The LTC2751A-16 provides
16-bitperformance(±1LSBINLandDNL)overtemperature
withoutanyadjustments.TheseSoftSpanDACsoffersix
outputranges—twounipolarandfourbipolar—thatcanbe
programmedthroughtheparallelinterface,orpinstrapped
for operation in a single range.
These parts use a bidirectional input/output parallel in-
terface that allows readback of any on-chip register. A
power-oncircuitresetstheDACoutputto0Vwhenpoweris
initiallyapplied.AlogiclowontheCLRpinasynchronously
clears the DAC to 0V in any output range.
The parts are specified over commercial and industrial
temperature ranges.
