Hi,

We have requirement for 4 channel line driver IC. Requirement is to take 4 channel single ended audio from DSP and provide pre-outs in the audio head unit for external amplifier connection.

I could see only DRV134/5 in our portfolio. Please let us know the best way to meet this requirement. 

Regards,

Praveen GD

    Hi Praveen,
    I am not aware of any other purpose-built line drivers in our portfolio. If a true differential output is required (for driving a balanced output), I'd recommend building a line driver from an automotive-qualified op amp (opa1641/42 or opa1662, for instance). If these outputs are simple RCA jacks, then it may be adequate to simply drive them directly from an op amp as above.
