TDA7571 数据手册 ( 数据表 ) - STMicroelectronics

Description
The TDA7571 i is a fully digital switchmode power audio amplifier with I2S digital input and PWM output.
The maximum output current and voltage swing are depending by the output circuitry (power supply, external power transistors and sensing resistors). The device can work as a stereo single-ended channels or a mono bridge power amplifier.
