Part Number: ISO224
Hi team,
According to below thread, ISO224 has internal charge pump so that ISO224 can accept bipolar input with only positive supply.
Since ISO224 can accept ±12V with VDD1=4.5~18V, power tree seems to be following.
Is this understanding correct?
VDD1 4.5~18V → Reg 4.5V → Charge Pump(Boost ) about 15~18V for powering amplifier
→ Charge Pump(Inverting) about -15~-18V for powering amplifier
Best regards,
Shota Mago
