LC2 MOS 3.3/5伏低功耗12位数模转换器AD7564数据表
分享资料个
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.
