DESCRIPTION
18-Bit SoftSpan IOUT DAC
with Parallel I/O
The LTC2757 is an 18-bit multiplying parallel-input, cur-
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 specications, the LTC2757
also offers excellent AC specications, including 2.1μs
full-scale settling to 1LSB and 1.4nVs glitch impulse.
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.
