Analog Devices Inc. AD5360/AD5361 16/14位电压输出DAC

Analog Devices AD5360/AD5361 16通道16/14位DAC提供缓冲电压输出,其范围是基准电压的四倍。每个通道都有一个可编程增益寄存器和一个失调调整寄存器。设计人员可单独调整每个DAC的增益和失调,以去除误差。为进一步提高灵活性,该器件可分为两组,每组八个DAC。每组的输出范围可通过失调DAC独立调整。AD5360/AD5361 DAC确保在宽电源电压范围(−4.5V至−16.5V VSS和+8V至+16.5V VDD)内正常运行。输出放大器的裕量要求是1.4V。AD5360/AD5361 DAC配有高速四线串行接口。4线串行接口兼容SPI、QSPI™、MICROWIRE™和DSP接口标准,可处理高达50MHz时钟速率。所有输出可通过将LDAC输入调低同时更新。

The Analog Devices AD5360/AD5361 DACs offer guaranteed operation over a wide supply range with VSS from -4.5V to -16.5V and VDD from +8V to +16.5V. The output amplifier headroom requirement is 1.4V. AD5360/AD5361 DACs have a high-speed 4-wire serial interface. The 4-wire serial interface is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards and can handle clock speeds of up to 50MHz. All the outputs can be updated simultaneously by taking the LDAC input low.
