Frequently Asked Questions

What output power does the TAS5112ADFDG4 deliver, and over what frequency bandwidth?

The TAS5112ADFDG4 delivers 62 W nominal output power per channel across a 20 kHz audio bandwidth. This makes it well suited for driving full-range speakers in stereo home audio systems and powered bookshelf speaker designs.

What supply voltage range does the TAS5112ADFDG4 require, and how does that affect power supply design?

The TAS5112ADFDG4 requires a supply voltage between 16 V and 30.5 V, giving designers flexibility to use standard 19 V laptop-style adapters or 24 V rail power supplies. This range supports both compact desktop speakers and larger home theater amplifier builds.

How does the 56-pin HTSSOP exposed-pad package help manage heat in high-power audio applications?

The 56-pin HTSSOP package includes an exposed thermal pad on its underside, allowing direct heat transfer to a PCB copper pour or heatsink layer. At 62 W per channel, this is essential: without adequate thermal management, junction temperatures would exceed safe limits during sustained high-volume playback.

When would an engineer choose TAS5112ADFDG4 over a Class-D amplifier for the same output power?

A Class-AB device like the TAS5112ADFDG4 is preferred when audio purity is paramount and switching noise from Class-D would interfere with sensitive analog circuitry. It also avoids the need for output filter inductors, reducing BOM complexity for designs using 4-ohm to 8-ohm speaker loads at up to 62 W.
