Hello
My customer is using TPA2006 for Gas-alarm sensor.
They want to have ' Detection of speaker- disconnection' feature for next model using external circuit.
In this background, output impedance in case /SD=L is very important.
*
As per customer's test result, output impedance of TPA2006 in /SD mode is 1Kohm.
Then I intend to recommended to use TPA3111 , but it should be also 1kohm... see my TINA TI result for your refference( attached)
Do you think this is reasonable?

Competitor is NPC SM6803A whose output impedance is a few handred Kohm ( as per customer says).
Do you have any recommended low power Mono-D-amp with High impedance ( over 100kohm) in shutdown mode?
Best Regards
