Hi ,

Anyone know what is this amp is based upon ? Is it chip or BJT inside?.
It says it has ,

High Instantaneous Current Capability (HCC) : ±45 amps.

Anyone know?. I thought of buying it. if it is chip , i won't buy , i will build one. If it is BJT inside , it is worth the buy.

Thanks
Alexk

Sounds more like MOSFET with that high current capability.

Discrete output IIRC, but don't remember any more if it was BJTs or MOS... possibly something similar to 2SC1302/2S3281 if it's BJT.
