EVAL-AD5064-1EBZ: AD5064 全精度16-Bit电压输出型nanoDAC™,SPI接口,2.7 V～5.5 V电源电压,采用TSSOP封装
The AD5024/AD5044/AD5064 are low power, quad 12-/14-/ 16-bit buffered voltage output nanoDAC® 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, QSPI™, MICROWIRE™, 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.
AD5024/44/64是低功耗、四通道12-/14-/16-bit缓冲电压输出型数模转换器,提供1LSB INL精度,每通道DAC可使用独立的参考源,也可以共用一个参考源,它采用2.7 V～5.5 V单电源供电。AD5024/44/64还能够提供±1 LSB的差分精度。该器件采用通用的3线低功耗Schmitt触发器串行接口,能够在高达50 MHz的时钟速率下工作,并且与标准的SPI®、QSPI®、MICROWIRE®和DSP接口标准兼容。该器件还集成了片上参考缓冲器。AD5024/44/64集成了上电复位电路,在没有发生有效写操作时,确保DAC的输出在上电时为零电位或中间电位。AD5024/44/64具有待机功能,在5 V电源供电时电流消耗减少到400 nA,并且在待机模式下具有可软件选择的输出负载 。该器件的总非调整误差小于2 mV。
