Part Number: LM3886
Other Parts Discussed in Thread: TINA-TI

Our customer would like to configure the output (@ 2ohm, Vs=+/-15V) of LM3886.

So they need the graph data as follows.

(1) Supply Current vs Output Voltage @ Vs=+/-15V

(2) Output Power vs Load Resistance @ Vs=+/-15V

(3) Output Power vs Supply Voltage @ RL=2ohm

(4) Mute Attenuation vs Mute Current @Vs=+/-15V,RL=2ohm,Vo=13V

If you have the data, would you please show that?

Thank you in advance.

Best regards,

Hi Takishin-san,

Unfortunately I'm not able to setup a test circuit to generate this data. All data available is contained in data sheet.
You could use the TINA-TI reference design to perform some testing. Considering the relatively low supply voltage the device could drive 2-Ohm load safely.
