From the datasheet:
..."The NJM2043 is a bipolar operational amplifier which is designed as low noise version of the NJM4558 with high output current and fast slew rate ( 6V/μs ) and wide unity gain bandwidth ( 14MHz ) constructed using New JRC Planar epitaxial process.
■ FEATURES
● Operating Voltage ( ±4V~±22V )
● High Output Current ( 25mA. )
● Slew Rate ( 6V/μs typ. )
● Unity Gain Bandwidth ( 14MHz typ. )
● Package Outline DIP8,DMP8,SIP8
● Bipolar Technology..."

As a follow up to my previos post, I will add two of my RIAA EQ projects one of them ( 1981 Sharp/Optonica ) , tested and working ! 🙂 One based on Optoinica's proven design ( around LF353 , which is very good for the job ), the other one is a Mitsubishi's design around the M5219P, I just finished an hour ago ( booth pin compatibale with 4558...) 😉 😎 🙂 .
The cost of these IC's is from 0,55$(LF353) to 2,20$(M5219FP, the smd type 😉 ) in Mouser, ect.

I can't edit my previous post , so here are some pics...
1-4. Optonica RIAA +/- 0.4% ,20Hz-20kHz , S/N 72.5dB
- based on LF353
• Low InputBiasCurrent50 pA Typical
• Low InputNoiseCurrent0.01pA/√Hz Typical
• Low SupplyCurrent3.6 mA Typical
• HighInputImpedance1012ΩTypical
• Internally-TrimmedOffsetVoltage
• GainBandwidth3 MHzTypical
• HighSlewRate13 V/μs Typical
5. Mitsubishi RIAA ,77dB, 10Hz-30kHz, THD=0.001%
- based on M5219P
...with this IC , and couple of 2SK109A, some may reach 85dB , 5Hz-100kHz, gain 35dB, the schematics are in the PDF file ....
