THS4151: THS4151ID current consumption

Conor
Guru 10090 points
Part Number: THS4151

Hi,

The data sheet states that when Icc Vcc=±15V Ta=full range, MAX:23mA. Is this correct in that on the +15V power supply side, the maximum is 23mA/2 = 11.5mA, and on the -15V power supply side, the maximum is 23mA/2 = 11.5mA? Or does it mean that the maximum power consumed by each power supply is 23mA?

Thanks,

Conor

    This device does not have a ground pin. ICC is defined as the current that flows into VCC+ and out of VCC−.

    Hi Conor,

    As Clemens stated, the quiescent current is defined as the current that flows into Vcc+ and out of Vcc-. Please note that this is only the current needed to keep the amplifier turned on. It does not include the power dissipated in the op amp's output stage to drive the load and the power dissipated by the load itself. This article goes over the basic power consumption of op amps (link).

    Thanks,

    Nick
