TDA1517ATW是NXP公司的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.  图1。TDA1517ATW 方框图  图2。TDA1517ATW BTL 应用方框图  图3。TDA1517ATW SE 应用方框图 (责任编辑：admin) |
