Product details

What this JFET op-amp brings to the board

The TL081HIDR is a single JFET-input operational amplifier from Texas Instruments in an 8-SOIC package. It delivers a 5.25 MHz gain-bandwidth product and a 20 V/µs slew rate, with a 1 pA input bias current that keeps high-impedance sensor signals clean. Supply range runs from 4.5 V to 40 V, and the push-pull output stage handles loads without external pull-up resistors.

Slew rate and bandwidth — what they mean for signal fidelity

The 20 V/µs slew rate supports 5.25 MHz gain-bandwidth product. For active filters or ADC driver stages, the 5.25 MHz GBW provides closed-loop gain before roll-off.

8-SOIC (3.90 mm width) — standard footprint, easy to hand-solder or hot-air rework. Pin 1 is clearly marked on the package top.

Marked as Active in production — no end-of-life notice on this variant.

Frequently asked questions

Is TL081HIDR RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest EU restriction levels for lead, mercury, cadmium, and other substances.

Will TL081HIDR work as a replacement for TL081CP?

TL081CP is a DIP-8 package; TL081HIDR is surface-mount 8-SOIC. Electrically the JFET input stage and 5.25 MHz GBW are the same family, but the package is not pin-compatible for through-hole boards. For a direct SMD replacement, TL081HIDR works if the board layout accepts SOIC.

What is the pinout of TL081HIDR?

Standard 8-SOIC op-amp pinout: pin 1 offset null, pin 2 inverting input, pin 3 non-inverting input, pin 4 V-, pin 5 offset null, pin 6 output, pin 7 V+, pin 8 NC. Pin 1 is marked on the package.

When sourcing TL081HIDR, what's the closest functional second-source — TLV9351IDCKR?

The TLV9351IDCKR is a general-purpose rail-to-rail op-amp with 3.5 MHz GBW and 20 V/µs slew rate, but it has a CMOS input stage (10 pA bias) versus the JFET input (1 pA bias) of the TL081HIDR. For high-impedance sensor applications where picoamp bias matters, the TL081HIDR is the better fit. For rail-to-rail output and lower offset, the TLV9351IDCKR is an alternative.
