TAS5352
125W 立体声数字放大器功率级
The is a high-performance, integrated stereo digital amplifier power stage designed to drive a 4- bridge-tied load BTL at up to 125 W per channel with low harmonic distortion, low integrated noise, and low idle current.
The TAS5352 has a complete protection system integrated on-chip, safeguarding the device against a wide range of fault conditions that could damage the system. These protection features are short-circuit protection, over-current protection, under voltage protection, over temperature protection, and a loss of PWM signal PWM activity detector.
A power-on-reset POR circuit is used to eliminate power-supply sequencing that is required for most power-stage designs.
