I do not mind if the pin out is not the same (DIL or SIL) but it must
be low noise and bandwidth for 10 MHz or better, below is the spec.
The circuit it is in has a supply voltage of 26 volts.
The main problem is the large output swing.
• Low noise: 1.0 µV total input noise
• High gain: 104 dB open loop
• Single supply operation
• Wide supply range LM387: 9 to 30V LM387A: 9 to 40V
• Power supply rejection: 110 dB
• Large output voltage swing (VCC - 2V)p-p
• Wide bandwidth 15 MHz unity gain
• Power bandwidth 75 kHz, 20 Vp-p
• Internally compensated
• Short circuit protected
If pin compatibility doesn't matter how about this old workhorse - NE5534.
Here is a dual. LM833
I think its gain of one stable.
Another precision single OP37, better pwr supply rejection if
thats inportant.
A little number shifting, a quad LM837
