Looking for op-amp for VCC=100/200V and output current of 5A.
Do we have solution?
Hi Eli,
This is not an easy requirement to meet with a monolithic because of the high voltage and high power required. None of our high-voltage operational amplifiers are capable of providing a 5 Ampere output current. The OPA454 is a +/-50 V (100 V) maximum operating voltage operational amplifier, but output current is about 50 mA maximum. A solution might be to team it up with a complementary pair of HV power MOSFETs, or HV Darlingtons (these may not exist).
