Product details

What this JFET op-amp delivers

The Analog Devices OP42GPZ is a single JFET-input operational amplifier in an 8-pin PDIP through-hole package. Its 50 V/µs slew rate and 10 MHz gain-bandwidth product make it a fit for fast-settling analog signal chains — DAC output buffers, waveform generators, and active filters where the signal edge matters. The JFET input stage keeps input bias current at 130 pA, which preserves accuracy in high-impedance sensor interfaces and photodiode amplifiers.

Output drive and quiescent draw

Each channel delivers 33 mA output current — enough to drive a load to ±10 V or feed a successive ADC input. Quiescent supply current is 5.1 mA, which is moderate for a fast JFET op-amp; not a low-power part for battery gear, but reasonable for a multi-channel board where the rail budget is a few tens of milliamps.

Frequently asked questions

What is the recommended replacement for OP42GPZ?

No official replacement is listed because the part is still active. For a surface-mount alternative in the same family, look at the OP42 family's SOIC variants — same JFET core, same slew rate, different footprint.

What is the difference between OP42GPZ and OP42?

OP42GPZ is the through-hole PDIP variant of the OP42 JFET op-amp. The 'GPZ' suffix indicates the 8-pin DIP package and ROHS3 compliance. The die and electrical specs (50 V/µs slew rate, 10 MHz GBW) are identical across the family.

Is OP42GPZ single supply?

Yes — the OP42GPZ can run from a single supply rail between 16 V and 40 V. The input common-mode range and output swing are specified for single-supply operation within that span.
