SLOS659 – JANUARY 2010

Dual Stereo Line Driver

The DRV604 Headphone stereo amplifier can also be used as Line Driver and has the same high output voltage

capability as the Line amp when driving 5k

Ω load impedances. This makes the DRV604 ideal for applications like

dual SCART outputs on LCD TV, or for multiple line outputs like in DVD or Blue-Ray players where 2x DRV604

can give a very space effective solution for a 8ch line output.

Capacitive Load

The DRV604 has the ability to drive a high capacitive load up to 220pF directly, higher capacitive loads can be

accepted by adding an output series resistor of 47

Ω or larger for the line driver output.

Layout Recommendations

A proposed layout for the DRV604 can be seen in the DRV604EVM user's guide, SLOU288, and the Gerber files

can be downloaded on www.ti.com, open the DRV604 product folder and look in the Tools and Software folder.

on these input pins and to ensure maximum stability of the DRV604.

Ground traces are recommended to be routed as a star ground to minimize hum interference.

PVDD, PVSS decoupling capacitors and the charge pump capacitors should be connected with short traces.

Footprint Compatible with the DRV603

The DRV604 stereo line driver section is pin compatible with the DRV603. A single PCB layout can therefore be

used with stuffing options for different output configurations.
