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.
