75-watt + 75-watt dual BTL class-D audio amplifier

• Support multiple configurations output:
• 75-W + 75-W output power at THD = 10% with RL = 4 Ω and VCC = 25.5V
• 55-W + 55-W output power at THD = 10% with RL = 6 Ω and VCC = 25.5V
• 1 x 110-W output power mono parallel BTL at THD = 10% with RL = 3Ω and VCC = 26V
• Wide-range single-supply operation (7 - 26V)
• High efficiency (η = 85%)
• Four selectable, fixed gain settings of nominally 20.8 dB, 26.8 dB, 30 dB and 32.8 dB
• Differential inputs minimize common-mode noise
• Standby and mute features
• Smart protection
• Thermal overload protection
• Output power limited by PLIMIT function
• Small offset less than 20 mV

The APA150 is a dual BTL class-D audio amplifier with a single power supply designed for home systems and active speaker applications.

It comes in a 38-pin SSOP(Shrink Small-Outline Package) package with slug-up to facilitate mounting a separate heatsink.
