JRC op amp 062D ?

[cmos]

Hello,
The op amp chip for the continuity beeper died in my meter again,
well it mite of got some help from a cap that still had a charge on it
somewere in the circuit I was checking. But it has been about 5 years
sence the chip went bad last. But the last time I replaced it I took
one out of a simalar meter that had been fried. Now that I have to
replace it again I need to find one somewere. This is an 8 pin
op amp chip, with the writeing on it as follows:
062D
JRC
0012B

I have not been able to cross refrence it of find a replacement for
it. Can any one tell me were to get this ?

Anyone know of a LM series equevlent ?

Or a cross to an ECG ?

Thanks.

Try a TL062 from TI, Motorola or ST.
IC-Master lists these as JFET dual op-amps
(Full JRC type no. is NJM062D)

Is Pin 8 connected to anything. If not its a 741 clone. If
pin 8 is connected its probably an LM358 clone. Draw out the
circuit and if Pin 8 is + and Pin 4 is - and output seems to
come from pins 1 and 7, its 95% certain an LM358 could work.

It's Video amplifier with 2 differencial output.
Maybe NJM592D.
and second sorce of TI.
