AD5325ARM: 2.5 V至5.5 V、500 µA、双线式接口、四通道、电压输出12位DAC,采用10引脚MicroSOIC封装
The AD5305/AD5315/AD5325 are quad 8-,10-and 12-bit buffered voltage output DACs in a 10-lead microSOIC package that operate from a single 2.5 V to 5.5 V supply consuming 500 µA at 3 V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/µs. A 2-wire serial interface is used which operates at clock rates up to 400 kHz. This interface is SMBus-compatible at VDD <3.6 V. Multiple devices can be placed on the same bus.
AD5305/AD5315/AD5325分别是四通道8/10/12位、缓冲电压输出DAC,提供10引脚microSOIC封装,采用2.5 V至5.5 V单电源供电,3 V时功耗为500 µA。这些器件内置片内输出放大器,能够提供轨到轨输出摆幅,压摆率为0.7 V/μs。所用的双线式串行接口能够以最高400 kHz时钟速率工作。当VDD<3.6 V时,此接口为SMBus兼容。多个器件可以共用同一总线。
