Power buffer amplifier (Unity-gain stable)

Nasir Alfaraj
Prodigy 30 points

Hello,

I need a power buffer amplifier with high output current: Io>650 mA RMS to drive a coil. I have attached the application circuit and input voltage waveform. The voltage is non-sinusoidal, with peak to peak value of 43.2 V. The frequency is 157.2 kHz, but it can reach 210 kHz. Any help is really appreciated.

Sincerely,

Nasir

    Nasir,

    This sounds like a very specialized requirement. The combination of speed and voltage and current is outside the range of our product line. I suggest that you check Apex Microtechnology as they have some products that might be suited. I expect that they will be quite expensive.

    Regards, Bruce.
