DESCRIPTION
Dual Current Output
12-/14-/16-Bit SoftSpan
DACs with Parallel I/O
The LTC
®
2753 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 asyn-
chronously clears the DACs to 0V in any output range.
