TDA1517ATW设计的8W BTL音频功率放大技术
TDA1517ATW：8 W BTL or 2 × 4 W SE power amplifier
The TDA1517ATW is an integrated class-AB output amplifier contained in a plastic heatsink thin shrink small outline package (HTSSOP20). The device is primarily developed for multimedia applications.
TDA1517ATW 主要特性：
Requires very few external components
Flexibility in use: mono Bridge-Tied Load (BTL) and stereo Single-Ended (SE); it should be noted that in stereo applications the outputs of both amplifiers are in opposite phase
High output power
Low offset voltage at output (important for BTL)
Fixed gain
Good ripple rejection
Mode select switch (operating, mute and standby)
AC and DC short-circuit safe to ground and VP
Electrostatic discharge protection
Thermal protection
Reverse polarity safe
Capable of handling high energy on outputs (VP = 0 V)
No switch-on/switch-off plop
Low thermal resistance.
