AD5024/AD5044/AD5064分别是低功耗、四通道、12/14/16位缓冲电压输出nanoDAC(R) DACs 相对精度特性为1 LSB INL(积分非线性)和1 LSB DNL(微分非线性),具有独立的参考电压引脚 , 可以采用4.5 V至5.5 V单电源供电 。 此外还提供±1 LSB的差分精度特性 。 这些DAC采用多功能三线式、低功耗、施密特触发串行接口,能够以最高50 MHz的时钟速率工作,并与标准SPI、QSPITM、MICROWIRETM、DSP接口标准兼容。同时片内集成基准电压缓冲。AD5024/AD5044/AD5064均内置一个上电复位电路,确保DAC输出上电至零电平或中间电平,并保持该电平,直到该器件执行一次有效的写操作为止。这些器件还具有省电特性,在省电模式下,器件在5 V时的典型功耗降至400 nA,并提供软件可选输出负载。总非调整误差小于2 mV。
The AD5024/AD5044/AD5064 are low power, quad 12-/14-/ 16-bit buffered voltage output nanoDAC(R) DACs that offer relative accuracy specifications of 1 LSB INL and 1 LSB DNL with individual reference pins and can operate from a single 4.5 V to 5.5 V supply. The AD5024/AD5044/AD5064 parts also offer a differential accuracy specification of ±1 LSB. The parts use a versatile 3-wire, low power Schmitt trigger serial interface that operates at clock rates up to 50 MHz and is compati- ble with standard SPI, QSPITM, MICROWIRETM, and DSP interface standards. Integrated reference buffers and output amplifiers are also provided on-chip. The AD5024/AD5044/AD5064/AD5064-1 incorporate a power-on reset circuit that ensures the DAC output powers up to zero scale or midscale and remains there until a valid write takes place to the device. The AD5024/AD5044/ AD5064/AD5064-1 contain a power-down feature that reduces the current consumption of the device to typically 400 nA at 5 V and provides software selectable output loads while in power- down mode. Total unadjusted error for the parts is <2 mV.
