Typical Application
Description
The LTC2753 is a family of dual 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 LTC2753A-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 LTC2753 DACs use a bidirectional input/output parallel interface that allows readback of any on-chip register. 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 specied over commercial and industrial temperature ranges.
