DAC121C081是一个12位，单通道，电压输出数字 - 模拟转换器（DAC），工作于+2.7 V至5.5V电源供电。
输出放大器允许轨到轨输出摆幅和8.5μsec解决时间。
DAC121C081使用的电源电压作为参考提供最宽的动态输出范围，典型功耗为132μA，而在5.0V的工作。
It is available in 6-pin TSOT and LLP packages and offers three address options (pin selectable).
作为替代方案，DAC121C085提供9个我

C-compatible serial interface that operates in all three speed modes, including high-speed mode (3.4MHz).
外部地址选择引脚，允许DAC121C081或9 DAC121C085每2线总线设备。
的DAC121C081是可以提供额外的地址选项的引脚兼容的替代品。
DAC121C081和DAC121C085每个有一个16位的寄存器，它控制的运作模式，掉电条件，并输出电压。
A power-on reset circuit ensures that the DAC output power is up to zero volts.
Power-down function reduces power consumption by less than one microwatt.
Their low power consumption and small package make these DACs an excellent choice for battery-powered devices.
Each DAC operates over an extended industrial temperature range of -40°C to +125°C
DAC121C081和DAC121C085是8和10位分辨率，还提供引脚兼容的DAC系列的每一部分。
The 8-bit DAC sees DAC081C081 and DAC081C085.
10位DAC看到DAC101C081和DAC101C085。
