The two layers safeguard signal integrity and keep noise from the reference clock and DSP from bleeding into the amplification circuit.\u003c\/p\u003e\n\u003ch3\u003eLow Power Consumption and High Compatibility\u003c\/h3\u003e\n\u003cp\u003eDiscrete resistor network DACs have low power consumption compared to other integrated DAC designs, and minimize power drain from the mobile source. Combine the DAC design with a carefully designed amplification circuit and RU7 manages a low 100mA power drain.
