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 (±1LSBINL 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 interface 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 temperature ranges.
