Product DetailsThe AD5678 is a low power, octal, buffered voltage-output DAC with four 12-bit DACs and four 16-bit DACs in a single package. All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design.
The AD5678 utilizes a versatile 3-wire serial interface that operates at clock rates of up to 50 MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards. The on-chip precision output amplifier enables rail-to-rail output swing.
- Octal DAC (four 12-bit DACs and four 16-bit DACs).

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The AD5678 evaluation board is designed to help users quickly prototype new AD5678 circuits and reduce design time. The AD5678 operates from a single 2.7 V to 5.5 V supply.
For full data, see the AD5678 data sheet, which must be consulted in conjunction with UG-987 when using the evaluation board.
The evaluation board interfaces to the USB port of a PC via the SDP-B board. Software is available for download to allow the user to program the AD5678.
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.
