CDCLVP110 power consumption

Hi,

In the datasheet,

Vcc=0V, Vee=-2.375V to -3.8V, Iee=min 45, max 82mA, Icc=max 370mA.

If use 6ch of 10ch, how can I calculate power consumption?

Do I have to do Iee+Icc*6/9?

    When 6 loaded outputs (and 4 unused outputs unloaded/open), the total supply current from the positive power supply is as follows:

    Isupply = Iee_max + (Icc_max - Iee_max)*(6/10)

    The total power (Isupply * Vs_max) will be dissipated in the device and output load resistors.  You can estimate output load power to be ~50mW/output pair.  To get the device power consumption, subtract total load power from the total power.
