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.

Product Details

The Analog Devices AD5668 evaluation boards, the EVALAD5668SDCZ and EVAL-AD5668SDRZ, are designed to help customers quickly prototype new AD5668 circuits and reduce design time. The AD5668 operates from a single 2.7 V to 5.5 V supply. The device incorporates an internal 1.25 V or 2.5 V on-board reference to give an output voltage span of 2.5 V or 5 V, respectively. The on-board reference is off at power-up allowing the use of an external reference; the REF195 is used on this evaluation board. The device must be written to after power-up to turn on the internal reference.

Consult the AD5668 data sheet, available from Analog Devices, in conjunction with this user guide when using the evaluation board.

The evaluation board interfaces to the USB port of a PC via the SDP. Software is available with the evaluation board, which allows the user to easily program the AD5668.
