What this quad J-FET op-amp brings to the breadboard
The TL064CN is a quad J-FET input op-amp from Texas Instruments packing four independent amplifiers in a single 14-pin DIP. Each channel draws just 200µA supply current, making it a solid pick for battery-conscious or multi-stage analog processing where you need four gain blocks without the power penalty of a general-purpose bipolar quad. The J-FET inputs give you 30 pA input bias current — useful when you're buffering high-impedance sources like photodiodes or piezo sensors without loading them down. With a 1 MHz gain-bandwidth product and 3.5V/µs slew rate, it handles audio-band signals, active filters, and slow control loops comfortably. The through-hole package means you can breadboard it, socket it, or hand-solder it without a reflow oven — great for a weekend project or a prototype run.
Lifecycle and sourcing reality
The TL064CN is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is on record, so it remains a viable choice for both new designs and production replenishment. Sourcing is through independent distribution; we can quote current pricing and lead time against an RFQ. Availability is confirmed at quote time — no stock promises here, just a straight answer on what's available when you ask.
