Has anyone heard of this chip (HA17082) ? I'm having great difficulty finding a data sheet for it since I can't find a listing of it anywhere. Its an 8-pin dip device, don't know whether its an opto or op-amp, etc. There's also PS written below on the package, and 4F1 below that if its of any help in identifying the chip. Any help appreciated Dan dzorde at geocities.com
