Audio power amplifier based on TDA7297

Overview

TDA7297 is an audio power amplifier integrated circuit produced by Philips and is used in televisions and audio equipment. TDA7297 is a two-channel stereo power amplifier integrated circuit with MUTE (mute) control function. Its output power is QWX2o. The audio output of TDA7297 is BTL mode, which is suitable for a wide power supply voltage range (6-18 V). And has short circuit protection and overload protection functions.
TDA7297 adopts single row and double row 15-pin package. The operating voltage is 6.5-18V, up to 20V; the operating current is 2A, the output power is 2x15W (VCC = 16.5V, RL = 8W, f = 1kHz, Tamb = 25°C), and the operating temperature is 0~70°C. It is a stereo audio power amplifier circuit. It contains two audio signal power amplifier circuits and has mute and standby control functions.
