What depth detector THAT That EnoughComment
-
hello i measured pin 6 of NE 5534 (Testpoint 2) first test for my new poscope mega1+
and just want to know if that what i can see is good or not
i suppose it is the pulse and the falling side says damping resistor is nearly ok?
right? thx
kind regardsComment

NE5534 and NE5532 are similarComment
-
NE5532, contains two (2) internal amplifiers.
NE5534, contains only 1 (one)

NE5532 may be used in place of ne5534Comment

Just compare the datasheets step by step...

What changes should I do to replace the ne5534 tl071Comment
-
NE5534 is offset compensated against the positive, while TL071 is compensated against the negative rail. And not at the same pins.
NE5532 does not have offset compensation as 5534 does. The offset could be tweaked by adjusting the resistance at the inverting input, however, increasing it would spoil noise performance.
TL071 is much noisier than 5534.Comment

take lt 1115.
can anybody say wether the curve posted above is ok

Hi Bernte,
There are a few posts on here that show curves similar to yours I think (i may have posted a few myself). Have a look and compare yours to those.
It's been a while since i looked at a PI curve!

That damping resistor might be OK for the coil but the flyback looks like ~70us duration to settle (310us-238us).Originally posted by bernte_one View Post
Did you have the coil resting near something metallic?Comment

Hi friends,
I am from India (maharashtra). I'm studying at diploma in electrical engg.
I made pi detector but they have no good deep range so plz help which is best for gold nuggets and they have good deep rang (minimum 3 foot/36 inch)
Thanks,Comment
