MAXIM INTEGRATED PRODUCTS  MAX5385EUT+T  数模转换器, 低功率, 8 bit, 串行, 2.7V 至 5.5V, SOT-23, 6 引脚

The is a low power, 8bit digital to analogue converter DAC with 3-wire serial interface in 6 pin SOT-23 package. This device has an internal reference equal to 0.9 x VDD, it require an extremely low supply current of only 150µA typ and provide a buffered voltage output. It power-up at zero code and remain there until a new code is written to the DAC registers. It provides additional safety for applications that drive valves or other transducers that need to be off on power-up. This device is used in automatic tuning VCO, power amplifier bias control, programmable threshold levels, automatic gain control and automatic offset adjustment.
