Utsource certified used parts
Utsource certified used parts provide the following guarantees:
1. Utsource will inspect the goods, including appearance inspection (no serious damage to the appearance), select qualified and honest suppliers, and ensure 98% qualification rate.
2. Some parts are tested by machine.
3. Utsource certified parts can be returned and refunded unconditionally within 60 days.
Description
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
