Hello,
I bought operational amplifier OPA4830. TSSOP14 package with 4 operational amplifiers inside. Datasheet: here
1st - OP AMP I use as a summer
2nd - integrator
3rd - trigger
4th - voltage follower
I use +/- 5V power supply and when I turn it on, the chip become hot and strange sound comes from it. Also in Power supply display shows current consumtion: 0,11A!!!
When I use other OP AMPS in the same PCB, for example (LM324N), everything works fine, so in circuit there isn't problem.
Any ideas?
Thanks.
