I just wanted to ask the total power consumed by ADCMP581.
As per data-sheet:
Positive Supply Current: IVCCI: VCCI = 5.0 V, 50 Ω to −2 V: 6 mA
Negative Supply Current: IVEE: VEE = −5.0 V, 50 Ω to −2 V: −25 mA
Power Dissipation: PD: 50 Ω to −2 V: 155 mW
My question is, what about power dissipation, This can not be from supply current as it is only 129mW, and also it has to drive a 40 mA current at output.
So, where this dissipated power is coming from?
