Product Details
The LTC2756 is an 18-bit multiplying serial-input, current-output digital-to-analog converter. LTC2756A 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 3-wire SPI serial interface or pin-strapped for operation in a single range.
Any on-chip register (including DAC output-range settings) can be read for verification in just one instruction cycle; and if you change register content, the altered register will be automatically read back during the next instruction cycle.
Voltage-controlled offset and gain adjustments are also provided; and the power-on reset circuit and CLR pin both 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.
