Part Number: TL071H
Other Parts Discussed in Thread: UA741, TLV170

Hi,

My customer is considering to use TL071H instead of NJM741.

Will you tell me any other appropriate device than TL071H if possible?

Thank you for your support.

Best Regards,

The NJM741 is a clone of the UA741.

Other devices like the TL071H or TLV170/1/2 have better electrical characteristics (faster with less power).

Hi Takumi,

the TL071H is a 5MHz OPAmp with a slew rate of 20V/µs while the NJM741 can only 1MHz and 0.5V/µs. So the TL071H is much faster than the NJM741. Replacing a slow OPAmp by a much faster OPAmp in an already existing design can make issues. The customer should consider this.
