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.

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
