Texas Instruments PTAS5755MDFDR

The TAS5755M is functionally equivalent to the TAS5731M, but in a Pad-Up design that allows the device to create more power without experience a shutdown due to thermal limitations of a pad-down device.

Like the TAS5731M, the TAS5755M is a very flexible device, offering output configuration support for 2.1, 2.0, and mono applications. Single chip 2.1 is accomplished by running each of the Left and Right Speaker from an independent half-bridge and the subwoofer from a dedicated full-bridge. Oversampling, combined with a fourth-order noise shaper, provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.

A powerful output stage made up of 80-mΩ output MOSFETs coupled with a pad-up design to allow the use of a heatsink, enables the device to make as much as 2 × 50 W for a 6-Ω load. Conversely, in mono mode, it can make as much as 1 × 70 W continuously with a 4-Ω load.

Audio processing for the device consists of Stereo, Mono, and 2.1 signal mixing, as well as DC blocking filters, 8 BiQuads for L and R and 2 Biquads for the subwoofer channel. In addition to equalization, power limiting is accomplished by a two band Log-style DRC. A separate single band DRC is provided for the subwoofer.
