NJU8714 NJU3555 www.DataSheet4U.com STEREO BTL OUTPUTS SWITCHING DRIVER FOR Class D AMPLIFIER GENERAL DESCRIPTION The NJU8714 is a stereo BTL outputs switching driver for class D amplifier. It receives PWM/PDM signals from DSP outputs, and drives headphones or speakers by BTL outputs. Output drivers are composed of Series-Connected N-channel FETs, and output voltage levels can be controlled by variable power supply with keeping all of input signal information. The NJU8714 incorporates BTL outputs amplifiers, which eliminate AC coupling capacitors. Also, it provides “SEL” terminal which selects “Synchronous” or “Asynchronous”. “Asynchronous” can be reduced the operating current. Therefore, it is suitable for portable audio set and others.
