Product Details
The AD7564 contains four 12-bit DACs in one monolithic device. The DACs are standard current output with separate VREF , IOUT1 , IOUT2 and RFB terminals. These DACs operate from a single +3.3 V to +5 V supply.
The AD7564 is a serial input device. Data is loaded using FSIN, CLKIN and SDIN. Two address pins A0 and A1 set up a device address, and this feature may be used to simplify device loading in a multi-DAC environment. Alternatively, A0 and A1 can be ignored and the serial out capability used to configure a daisy-chained system.
All DACs can be simultaneously updated using the asynchronous LDAC input, and they can be cleared by asserting the asynchronous CLR input.
The device is packaged in 28-pin SOIC, SSOP and DIP packages.
APPLICATIONS

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.
