The LTC2755 is a family of quad 12-, 14-, and 16-bit multiplying parallel-input, current-output DACs. These DACs operate from a single 2.7V to 5.5V supply and are all guaranteed monotonic over temperature. The LTC2755A-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.

The LTC2755 DACs use a bidirectional input/output parallel interface that allows readback of any internal register, including the DAC output span settings. A power-on reset circuit resets the DAC outputs to 0V when power is initially applied. A logic low on the CLR pin asynchronously clears the DACs to 0V in any output range.

The parts are specified over commercial and industrial temperature ranges.
