High-speed general-purpose op amp in a hermetic ceramic LCC
Its headline specs — 175 MHz gain-bandwidth product and 300 V/µs slew rate — put it in the fast-settling class for pulse amplifiers, video distribution, ADC drivers, and wideband instrumentation front-ends. The 20-lead ceramic LCC package (8.89x8.89 mm) is hermetic and surface-mountable, required for programs that demand MIL-STD screening or operate in sealed, high-vibration environments.
The 300 V/µs slew rate means this op amp can swing a 10 V output step in about 33 ns — fast enough to reproduce 10 MHz square waves with reasonable fidelity. The 175 MHz GBW supports closed-loop gains of 10 at 17.5 MHz, or unity-gain bandwidths up to the GBW itself, so it works as a video line driver or a wideband transimpedance amplifier. Input offset voltage is 2 mV typical, and input bias current runs 2.5 µA — bipolar input stage, so source impedance matters. Supply current is 5 mA quiescent, which is moderate for this speed class. Supply span from 4.75 V to 32 V covers standard ±5 V, ±12 V, and ±15 V split rails, or a single 5 V to 28 V rail. The wide range is useful when retrofitting into legacy military power buses that may not be tightly regulated.
Temperature grade and package — built for the harsh stuff
It belongs in avionics black boxes, satellite payload electronics, missile guidance, and downhole drilling tools where the ambient can exceed 85°C and the board sees thermal cycling. The 20-lead ceramic LCC (also called 20-LCCC) is hermetic — no moisture ingress, no plastic package cracking at extreme temperatures. Surface-mount, but the ceramic body means it handles reflow or hand-soldering with care; the coefficient of thermal expansion is closer to alumina substrates than FR-4, so the board layout should match the package footprint exactly.
Lifecycle and compliance — active, but RoHS-exempt
For new designs requiring a MIL-screened high-speed op amp, this is a qualification-safe choice. It is RoHS non-compliant (leaded solder finish on the ceramic package), which is standard and expected for hermetic military/space components. Most defence and aerospace contracts have RoHS exemptions for these parts. If your BOM mandates RoHS compliance, this part will not pass the declaration — you would need to look at a plastic-packaged equivalent with different reliability screening.
Sourcing this part — what to expect
This is not a commodity op amp you will find on every distributor shelf. The 883-screened ceramic LCC variant is a specialty military line. We source it through our independent distribution network, confirmed against the National Semiconductor (now Texas Instruments) brand and date codes. If you are filling a BOM line for a repair or a production run, send the RFQ — we quote to order, not from a static shelf count.
