AD5317ARU: +2.5 V至+5.5 V、400µA、四通道、轨到轨输出10位DAC
The //AD5327 are quad 8-, 10-, and 12-bit buffered voltage-output DACs, in a 16-lead TSSOP package, which operate from a single 2.5 V to 5.5 V supply consuming 400 µA at 3 V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/µs. The AD5307/ AD5317/AD5327 utilize a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards.
AD5307/AD5317/AD5327分别是四通道8/10/12位、缓冲电压输出DAC,提供16引脚TSSOP封装,采用2.5 V至5.5 V单电源供电,3 V时功耗为400 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0.7V/µs。AD5307/AD5317/AD5327采用多功能三线式串行接口,能够以{zg}30 MHz的时钟速率工作,并与标准SPI、QSPI、MICROWIRE、DSP接口标准兼容。
