JFET quad op-amp — 5 pA input bias, 1 MHz GBW, 14-DIP
Its 1 MHz gain-bandwidth product and 3.5 V/µs slew rate suit it for precision analog signal conditioning — active filters, instrumentation amplifiers, and data-acquisition front-ends — where the 5 pA typical input bias current preserves accuracy from high-impedance sources like photodiodes or pH probes. Each amplifier draws 220 µA supply current, keeping the quad-channel power budget under 1 mA total.
The OPA4137P operates from a single or dual supply spanning 4.5 V to 36 V total. This covers the common 5 V, 12 V, and 24 V industrial rails without an extra regulator.
Package and mounting — DIP-14, through-hole
This package is breadboard-friendly, socket-compatible, and hand-solderable — a practical choice for lab prototypes, low-volume production runs, and service replacements on legacy analog boards. The 60 mA per-channel output current drives moderate loads like ADC inputs or headphone drivers directly.
