Technical Details & Description

Supply range and temperature — the practical envelope

Supply span runs from 10 V to 30 V.

Surface-mount 8-SOIC (3.90 mm body width). Standard footprint, no surprises for the pick-and-place. Tube shipment, so if your line is set up for tape-and-reel, factor in the handling step or request the alternate packing option at quote time.

Active lifecycle status per TI's record, ROHS3 compliant. No last-time-buy or obsolescence notice on this part. That means you can qualify it into a new design without worrying about a surprise EOL next quarter.

Frequently asked questions

What is the equivalent of THS3121ID?

The closest functional peer is the THS4215DRBT, a voltage-feedback amplifier with 350 MHz bandwidth and 970 V/µs slew rate. It is not a pin-for-pin replacement — the THS4215 uses voltage feedback versus the THS3121ID's current-feedback architecture, so the compensation and noise behavior differ. Evaluate the application circuit before swapping.

What is the pin configuration of THS3121ID?

The THS3121ID comes in an 8-SOIC package. The standard pinout for a single current-feedback op-amp in this package applies: non-inverting input, inverting input, output, positive supply, negative supply, and two null/offset trim pins. Refer to the TI datasheet for the exact pin mapping.
