The  NJM2043 specs are the same as the LM1458 / LM4558 exept for housing (= SIP).
 
 
 
They are high speed J–FET inputsingle operationalamplifiers incorporating well matched, high voltage J–FET, Low Noise and bipolar transistors in a monolithic integrated circuit. 
 
The devicesfeaturehigh slew rates, low input bias and offset currents, and low offset voltage temperature coefficient
