DESCRIPTION

–

The LTC

rent-output digital-to-analog converter that provides full 18-

bit performance—INL and DNL of ±1LSB maximum—over

temperature without any adjustments. 18-bit monotonicity

is guaranteed in all performance grades. This SoftSpan™

DAC operates from a single 3V to 5V supply and offers

six output ranges (up to ±10V) that can be programmed

through the parallel interface or pin-strapped for operation

in a single range.

In addition to its precision DC speciﬁ cations, the LTC2757

also offers excellent AC speciﬁ cations, including 2.1μs

full-scale settling to 1LSB and 1.4nV

The LTC2757 uses a bidirectional input/output parallel

interface that allows readback of any on-chip register,

including DAC output-range settings; and a CLR pin and

power-on reset circuit that each reset the DAC output to

0V regardless of output range.
