Other Parts Discussed in Thread: TINA-TI,
Tool/software: TINA-TI or Spice Models
Hello,
I am wanting to use the TPA3255 in a new design at my company that produce high power low frequency output Antennas for the security industry.
These antennas then power certain wireless devices that can then talk back to a system. Unfortunately I am not allowed to say more than this...
I want to use this class D amplifier over the traditional Class A/B design, however the Coil impedance isn't that of a standard Speaker.
I have been searching for a spice model so I can play around with values to check how to optimize the LC filter part.
I did look at the application note but it only mentions standard speakers and not arbitrary loads...
The out put is a 200Hz Sinusoidal wave with peak current of 20A and the impedance of the coil are the following:
Inductance (measured at frequency 1000 Hz) 1.5 mH
Resistance (DC measurement) 0.5 Ohm
Kind Regards
Daniel
