Hi Everyone, first post!
I am building a mobile phone from an old roatry phone I bought from a car-boot sale. Having had the idea I stumbled accross this:
http://www.sparkfun.com/tutorials/51
- which is fantastic and gives me a good start. I downloaded their schematics and noticed that they are using a different H-bridge (60V) from the one initially suggested (36v)
I have built the ringer bit which worked then I blew-up the (36v) H-bridge I had, so was hoping to upgrade to the one in their schematic.
I have purchased most of the stuff I need from Farnell - which has the best interface for selecting parts, but they don't seem have "NJM2670SMD" - it exists as I can find it on other sites - I just wanted to source everything from one place.
So does anyone know what other name this IC may go by? In fact RS have a NJM2670D2/3 but not an "SMD", whatever this is. Or can anyone suggest an alternative that can handle 50v+?
Cheers
