Description: AD5663,nanoDAC家族的一员,是一个低功率,双,16位缓冲电压DAC,从一个2.7 V至5.5 V供应和保证单调的设计。
AD5663需要外部参考电压设置DAC输出范围。包含部分的上电复位电路,确保了DAC输出大国为0 V或中级(AD5663-1)仍然存在,直到一个有效的写。部分包含一个省电功能,减少了设备的当前消费480 nA在5 V和提供software-selectable输出负载在省电模式。
这部分在正常操作的低功耗使它适合便携,电池供电设备。电力消耗是在5 V 1.25 mW,下降到2.4μW处于省电模式。
芯片上的精度的输出放大器AD5663允许轨到轨输出摆。
AD5663使用多才多艺,3-wire串行接口在50 MHz时钟频率和兼容标准SPI® ,QSPI™ ,导电带™ ,和DSP的接口标准。-The AD5663, a member of the nanoDAC family, is a low power, dual, 16-bit buffered voltage-out DAC that operates a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design.
The AD5663 requires an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V or midscale (AD5663-1) and remains there until a valid write takes place. The part contains a power-down feature that reduces the current consumption of the device to 480 nA at 5 V and provides software-selectable output loads while in power-down mode.
The low power consumption of this part in normal operation makes it ideally suited to portable, battery-operated equipment. The power consumption is 1.25 mW at 5 V, going down to 2.4 μW in power-down mode.
The on-chip precision output amplifier of the AD5663 allows rail-to-rail output swing to be achieved.
The AD5663 uses a versatile, 3-wire serial interface that operates at cloc

AD5551和AD5552可用在一个包。-The AD5551 and AD5552 are single, 14-bit, serial input, voltage
output DACs that operate a single 5 V ± 10 supply.
The AD5551 and AD5552 utilize a versatile 3-wire interface that
is compatible with SPI, QSPI, MICROWIRE, and DSP interface
standards.
These DACs provide 14-bit performance without any adjustments.
The DAC output is unbuffered, which reduces power
consumption and offset errors contributed by an output buffer.
With an external op amp the AD5552 can be operated in bipolar
mode generating a ±VREF output swing. The AD5552 also
includes Kelvin sense connections for the reference and analog
ground pins to reduce layout sensitivity. For higher precision
applications, please refer to 16-bit DACs AD5541, AD5542,
and AD5544.
The AD5551 and AD5552 are available in an SO package.
