Features and Benefits
- Eight 12-Bit DACs in One Package
- 4-Quadrant Multiplication
- Separate References
- Single +5 V Supply
- Low Power: 1 mW
- Versatile Serial Interface
- Simultaneous Update Capability
- Reset Function
- 44-Pin PQFP and PLCC
The AD7568 contains eight 12-bit DACs in one monolithic device. The DACs are standard current output with separate VREF, IOUT1, IOUT2 and RFB terminals.
The AD7568 is a serial input device. Data is loaded using FSIN, CLKIN and SDIN. One address pin, A0, sets up a device address, and this feature may be used to simplify device loading in a multi-DAC environment.
All DACs can be simultaneously updated using the asynchronous LDAC input, and they can be cleared by asserting the asynchronous CLR input.
The AD7568 is housed in a space-saving 44-pin plastic quad flatback and 44-lead PLCC.

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.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
