LMX2820: Estimation for power dissipation

franziskus

Part Number: LMX2820

Hi,

Is there a good formula to estimate the power dissipation of the device?
I think there was something on the GUI without an external current/voltage sensor?

I'm wondering if there's something better than just adding up the corresponding rows of Table 9-1. Maybe Table 9-1 is good enough.

Hi BR,
In TICSpro there is an approximate device current consumption calculation, you can use this to find the power dissipation of the device.

P = V * I ; V = 2.5V

Regards,

Vicente

Just wanted to clarify, V should be equal to 3.3V.
