Hello everyone,
I was curious whether it'd be possible to power DRV134 using 48V phantom power, directly from the balanced connection.
I am assuming it'd be necessary to create some sort of split supply (maybe using virtual ground generator TLE2426?), or is there another solution?
I was inspired by this article 0624.Mic_uses_phantom_pwr.pdf, where the balancing circuit is done by an opamp, and though that DRV134 may be even better solution for the job, since it has laser trimmer resistors for extra precession.
It is actually written by person from TI! :)
Thank you for any help,
Jonas
