LMH1218 - Disabling OUT1

Hello Team,

To power down the unused OUT1, I believe you only need to program REG 0x84 (REG 0x84 [1:0] = 2'b11)

If it is required to program, "OUT1_MUX_SELECT (REG 0x1E) to Mute" or any other registers, could you please let us know ?

Hi Kawai-san,

To power down the OUT1 output, you only need to program Reg 0x84[1:0] = 11'b.

There is no requirement to change the Reg 0x09[5] = 1, then Reg 0x1E = 111'b, as Reg 0x84[1:0] performs a redundant function in this situation. I also verified that there is no difference in current consumption when you use either of these methods to power down OUT1.

Thanks,

Michael
