The AD7568 contains eight 12-bit DACs in one monolithic device. The DACs are standard current output with seperate 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. APPLICATIONS Process Control Automatic Test Equipment General Purpose Instrumentation

Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_DD) is within the range of 4.5V to 5.5V.
   • Connect the power supply to the V_DD pin and ground (GND) pin.

2. Digital Inputs:

   • Digital input signals should be within the specified high (V_IH) and low (V_IL) levels.
   • Use appropriate logic levels to control the digital inputs.

3. Output Configuration:

   • The output voltage range is from 0V to 5V.
   • Ensure the load resistance and capacitance are within the specified limits to avoid excessive power dissipation.

4. Temperature Considerations:

   • For commercial applications, operate within 0°C to 70°C.
   • For industrial applications, operate within -40°C to 85°C.
   • Store the device within the storage temperature range of -65°C to 150°C.

5. Performance Parameters:

   • Monitor differential nonlinearity (DNL) and integral nonlinearity (INL) to ensure accurate conversion.
   • Verify the settling time for the desired accuracy in your application.

6. Handling and Storage:

   • Handle the device with care to avoid static damage.
   • Store in a dry environment to prevent moisture-related issues.

7. Testing and Troubleshooting:

   • Test the device under typical operating conditions to ensure it meets the specified parameters.
   • If issues arise, check the power supply, digital inputs, and load conditions for any discrepancies.
