Description for the TAS5634

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 TI’s 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.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
