TDA1517ATW是8W BTL或2 × 4 W SE音频功率放大器,在HTSSOP20封装内集成了AB类输出放大器,可用作单声道桥接负载(BTL)或立体声单端(SE)连接,具有良好的波纹抑制以及AC和DC短路安全。本文介绍了TDA1517ATW主要特性,方框图以及BTL和SE连接应用框图。

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.
