Dual JFET op amp in an 8-DIP — where it fits
The AD648JNZ: It delivers a 1 MHz gain-bandwidth product and a 1.8 V/µs slew rate, drawing just 340 µA total supply current for both channels. The JFET input stage keeps input bias current at 5 pA, suiting it for high-impedance sensor interfaces, precision integrators, and audio signal conditioning where low drift and low noise matter more than raw speed.
Package and mounting
The 1 MHz gain-bandwidth product sets the usable small-signal frequency range. The 1.8 V/µs slew rate limits full-scale output swing for audio and control loops.
Housed in an 8-DIP (0.300", 7.62 mm) through-hole package, the AD648JNZ is breadboard- and socket-friendly. Supply voltage spans 9 V to 36 V single or dual supply.
Active lifecycle, RoHS3 compliant
For new designs requiring a wider temperature range or surface-mount footprint, consider the ADA4062-4ARUZ (quad, -40°C to 125°C, SOIC) or the AD712JRZ (dual, 4 MHz, SOIC) — both JFET-input alternatives with different package and speed profiles.
