The LTC2757 is an 18-bit multiplying parallel-input, current-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 specifications, the LTC2757 also offers excellent AC specifications, including 2.1μs full-scale settling to 1LSB and 1.4nV•s 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.
