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
“Asynchronous”. “Asynchronous” can be reduced the
operating current. Therefore, it is suitable for portable
audio set and others.
