Dear Sir/Madam,

Actually we are about to use an 1.5watt audio output display with SGTL5000 codec IC, but speaker impedance is not mentioned in the display unit . so kindly let us know the Lineout speaker impedance & wattage of SGTL5000 or else whether it can support up to 1.5watt audio output since in datasheet LINEOUT Load is mentioned as 10kohm.

Regards,

Akshay

This could be message 3 but i had some issues when trying to request the following:

Where can i find the document/schema of SCH-26876 i searched for it but i did not saw it.

Hi Akshay,

 

The LINEOUT output impedance is 320ohms per channel. The lowest load impedance on the LINE out is expected to be 10k ohms

 

SGTL5000 and external amplifier can drive 1W/8ohm speakers (sheet 12 of schematic SCH-26876).
