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.
