12-/14-/16-Bit SoftSpan
DACs with Parallel I/O
The LTC
®
2751 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-bit performance (±1LSB INL and DNL) over temperature
without any adjustments. These SoftSpan™ DACs offer six
output ranges—two unipolar and four bipolar—that can be
programmed through the parallel interface, or pinstrapped
for operation in a single range.
These parts use a bidirectional input/output parallel in-
These parts use a bidirectional input/output parallel in-
terface that allows readback of any on-chip register. A
power-on circuit resets the DAC output to 0V when power is
initially applied. A logic low on the CLR pin asynchronously
clears the DAC to 0V in any output range.
The parts are specified over commercial and industrial
