TAS5612LA - Texas Instruments

TAS5612LA 125-W Stereo and 250-W Mono HD Digital-Input Class-D Power Amplifier

The TAS5612LA is a feature optimized class-D power amplifier based on the TAS5612A. The TAS5612LA uses large MOSFETs for improved power efficiency and a novel gate drive scheme for reduced losses in idle and at low output signals leading to reduced heat sink size. The unique preclipping output signal can be used to control a class-G power supply. This combin.
