Product details

Supply range and temperature — the practical envelope

Supply span runs from 10 V to 30 V. The -40°C to 85°C operating range covers industrial environments.

Package and mounting

Surface-mount 8-SOIC (3.90 mm body width). Standard footprint, no surprises for the pick-and-place. The supplier device package is listed as 8-SOIC — same as the case code. 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.

Lifecycle and sourcing reality

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. For current pricing and availability, this is sourced and quoted to order through independent distribution — submit an RFQ and the quote comes back with confirmed pricing and lead time for your quantity.

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.
