Hi Dave,

that sounds like a very useful product indeed; almost like a TW523-in-a-chip solutoin. I would look forward to its release.

In the mean time, my home brew circuit with off the shelf part also seems to be holding its own. In fact, the transformer I used (one from the set used in AM radios), gives out a signal 2 to 3 times in amplitude as the one from the RR501/TM751.

Regards,

Anand
