The TAS5634 is a PWM-input, Class-D amplifier power stage that supports 2 x 300 W (6 Ω) or 1 x 600 W (3 Ω) output power with a nominal power supply voltage of 58V. The 58V supply voltage provides support for higher impedance speaker loads including 6 Ω in BTL and 3 Ω in PBTL. Integrated MOSFETs and a new gate drive scheme provide high peak efficiency and low idle losses to reduce thermal solution size.
The TAS5634 uses a closed-loop feedback design with constant voltage gain. The internally matched gain resistors ensure a high power supply rejection ratio (PSRR) and low output noise due to switch mode power supplies (SMPS).
The TAS5634 is a fully integrated power stage compatible with TIs portfolio of digital-input (I2S) audio processors and modulators, like the TAS5548 and TAS5558, making it a complete digital-input Class-D amplifier. The TAS5634 is available in the surface mount 44-pin HTSSOP package and is part of a pin-compatible family of PWM-input Class-D power stages including the TAS5612LA, TAS5614LA and TAS5624A.
