How to increase Transmitting Power

user4731142
Prodigy 50 points

1) If I wanted to increase the power (watts) that is sent to the transducer, I assume can use something to boost the output voltage like a DC to DC boost converter? Is there another/better way to increase the excitation voltage without using the boost board that comes with the GASEVM? Lets say I wanted 400V.

 

2) For calculating the power in watts to the transducer, am I right in reading the data sheet that the max driving current on the output pin is 22mA and max voltage is 5.5V-.32V=5.18V? So it's delivering .11396 Watts?

3) Is there a way to increase the output drive current beyond 22mA?

    1. We only have the GASEVM boost circuit you point out that supports 30V excitation output. Sorry we don't have any other recommendation.
    2. Note TX is a pulsed output and those are the typical current and voltage numbers when the TX excitation pulses are generated. You can choose the number of burst pulses applied as 0 to 31.
    3. No
