2 Vrms的的DirectPath ™线路驱动器，具有可编程固定增益 2-Vrms DirectPath? Line Driver With Programmable-Fixed Gain
The is a single-ended stereo Line Driver designed to reduce component count and board space. It is ideal for single-supply electronics where size and cost are critical design parameters. The DRV612 does not require a power supply greater than 3.3V to generate its 5.6VPP output, nor does it require a split-rail power supply. Designed using s patented DirectPath technology, which integrates a charge pump to generate a negative supply rail that provides a clean, pop-free ground-biased output. It is capable of driving 2VRMS into a 600R load. DirectPath technology also allows the removal of the costly output DC-blocking capacitors. The device has fixed-gain single-ended inputs with a gain-select pin. Using a single resistor on this pin, the designer can choose from 13 internal programmable gain settings to match the line driver with the codec output level. It also reduces the component count and board space.
