Part Number: VCA824

Hi,

Let me confirm the value of "Max Iq".

There described the value is 38.5mA (Ta=-40℃ to 85℃) on the datasheet page6.

This value means at totally +/-5Vcc, not separate +Vcc/-Vcc,

that is to say, 38.5mA/+5Vcc and 38.5mA/-5Vcc (=77mA/+/-5Vcc), correct?

Thank you for your support.

Best Regards,

Takumi

Hi Takumi,

The 38.5mA specified is total Iq. That means that +5Vcc will source +38.5mA and -5Vee will sink -38.5mA. The 38.5mA total quiescent current flows in a closed loop between the supplies and through the amplifier.

Best regards,

Sean
