The LTC2751 is a family of 12-, 14-, and 16-bit multiplying 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) overtemperature without any adjustments. These SoftSpan™ DACs offer six output ranges — two unipolar and four bipolar — that can be programmed through the parallel interface, or pin strapped for operation in a single range.
These parts use a bidirectional input/output parallel interface that allows read back 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.
