Overview

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 V_REF, I_OUT1, I_OUT2 and R_FB 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.

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.
