JFET op-amp with 60 V/µs slew rate — what it means for the signal chain
The OP17EJ is a single J-FET input operational amplifier in a TO-99-8 metal can package, through-hole mount. It delivers a 30 MHz gain-bandwidth product and a 60 V/µs slew rate, making it suited for fast signal conditioning in test equipment, data acquisition front-ends, and active filters where settling time matters. The J-FET input stage keeps input bias current at 15 pA, preserving accuracy in high-impedance sensor interfaces. Supply range is 44 V total, with a quiescent current of 4.6 mA. Temperature grade is commercial (0°C to 70°C), so this part is intended for indoor, controlled-environment equipment — not extended industrial or automotive.
Through-hole TO-99 — legacy footprint, known reliability
The TO-99-8 metal can is a hermetic, round package with 8 leads. It is a through-hole part, so it requires a drilled PCB with plated holes.
Active lifecycle — no LTB pressure, but RoHS caveat
The OP17EJ carries an Active lifecycle status, meaning the manufacturer continues to produce it — no last-time-buy window to manage, and no forced redesign for obsolescence. However, it is marked RoHS non-compliant, so it is not suitable for new designs requiring lead-free assembly under EU RoHS exemptions. For legacy builds or military/avionics contracts that permit tin-lead solder, this part remains available through the independent distribution channel, sourced and quoted to order against an RFQ.
