Ben,
The recommendation for unused amplifiers (section 7.2) in this application note for a somewhat similar op amp should also apply to RC4136 (other than soft VOL).
Part Number: OPA1652 Other Parts Discussed in Thread: OPA2134 , RC4136 , OPA1678 , TINA-TI Have an active audio filter in an older piece of equipment that uses RC4136s. It is quite noisy. OPA2134 has been suggested as replacement, as well as OPA1652.…
Hi Tony,
C: Comercial Temperature Range (0 to 70oC)
N is the package naming. It shows the package in the dataseet.
The TL075 is actually the same device as the TL074, but with different pinouts.
If you are looking for drop-in device, then the…

Cimmaron (Brown Dog) is the best solution. Their adaptors are very small, within a DIP machine socket outline so they don't stick out on the sides. They are also gold flashed with gold Millimax pins. It's best to refit a machined socket when using them…

Mark,

I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
