The OPA1622 high current high temperature operational amplifier chip can be upgraded with dual operational amplifiers such as NE5532, OP275, OPA2604, etc. It has a high output current (145ma) and strong driving capability.
Adopting the original imported OPA1622 high current high temperature operational amplifier chip, adopting a chip to chip design, and using gold-plated round head pins for easy upgrading of ordinary operational amplifiers.
