Note.1) All voltage values are specified as VSS=0V.
Note.2) If the LSI is used on condition beyond the absolute maximum rating, the LSI may be destroyed. sing LSI within electrical characteristics is strongly recommended for normal operation. Use beyond he electrical characteristics conditions will cause malfunction and poor reliability.
Note.3) The relations of VDDO < VG must be maintained during operations.




Description

The NJU8714 is a stereo BTL outputs switching driver or class D amplifier. It receives PWM/PDM signals from SP outputs, and drives headphones or speakers by BTL utputs.

Output drivers of NJU8714 are composed of Series-Connected -channel FETs, and output voltage levels can be ontrolled by variable power supply with keeping all of nput signal information.

The NJU8714 incorporates BTL outputs amplifiers, hich eliminate AC coupling capacitors. Also, it provides SEL" terminal which selects "Synchronous" or Asynchronous". "Asynchronous" can be reduced the perating current. Therefore, NJU8714 is suitable for portable udio set and others.
