Maxim Integrated

1983

Maxim didn’t invent analog — it weaponised compatibility.

Maxim Integrated was a pragmatic analog IC company that prioritised compatibility, speed-to-market, and application-specific integration over architectural novelty. Its success came from solving narrow, persistent interface problems — not from inventing new physics or scaling digital logic.

    What it was

    Maxim was an analog and mixed-signal IC company — not digital, not software, not systems.

    The clone-first model

    It started by cloning other people’s chips — 24 second-source parts in year one.

    The chip that funded everything

    The MAX232 paid the bills — Maxim’s first profit came from one chip that solved a universal wiring problem.

    The wafer milestone

    Its 2010 300mm analog shipment was a late-stage manufacturing upgrade — not a new capability.

What it is and the problem it solves

Maxim Integrated was a semiconductor company solving the problem of interoperability and reliability in analog signal chains — especially where RS-232 communication, voltage regulation, and sensor interfacing demanded robust, pin-compatible parts.

How it works

Maxim Integrated designed, manufactured, and sold analog and mixed-signal integrated circuits. It built its early business on second-source products — drop-in replacements for existing ICs — and launched proprietary chips like the MAX600 and MAX232.

What works

Its second-source strategy worked immediately: 24 products in year one. The MAX232 worked well enough to drive profitability in 1987. Its focus on mixed-signal integration — combining analog functions with basic digital logic — solved real interface problems in industrial and computing gear.

What does not

Maxim did not pioneer new semiconductor process nodes or architecture paradigms. It did not achieve scale in digital logic, microprocessors, or memory. Its 300mm wafer shipment in 2010 was a manufacturing milestone, not a design innovation.

What it changes

It changed how analog ICs reached market: by prioritising compatibility, rapid time-to-volume, and application-specific integration over foundational research. It proved analog could be commercialised as a vertical stack — design, fab-lite manufacturing, and direct sales — rather than as a foundry service.

Is it worth your time

Yes — if you work with analog interfaces, legacy industrial or communications hardware, or discrete signal conditioning. Its product lineage remains embedded in real-world systems, but its relevance to new designs has declined since its 2019 acquisition by Analog Devices.

PhotoresistorA photoresistor detects light by changing resistance. It works via photoconductivity: photons excite electrons, lowering resistance. Resistance spans megaohms to hundreds of ohms. Response is slow — 10 ms to light, up to 1 s to dark. Temperature shifts its output. It is less sensitive than photodiodes or phototransistors. It suits only slow, coarse light-sensing tasks.

ASML1984ASML is the dominant supplier of photolithography machines for integrated circuit production. Founded in 1984 as a joint venture between Philips and ASM International, it inherited Philips’ stalled lithography project and initially had no market-ready product. Its first machine, the PAS 2000, failed commercially and technically. Success came with the PAS 5500 in the early 1990s. By 2002, ASML was the largest lithography supplier. It now leads in extreme ultraviolet (EUV) lithography—the only viable method for manufacturing the most advanced chips—and completed EUV machine development in the late 2010s. Competitors included Canon, Nikon, Ultratech, MKS Instruments, Lam Research, and Cadence Design Systems.

PhotolithographyPhotolithography is the foundational patterning method for integrated circuits. It uses light, masks, and photochemistry to define nanoscale features on silicon wafers. First named in 1958, it enabled the shift from hand-assembled transistors to mass-produced chips. It works at wafer scale, with high precision and low per-chip cost—but only in planar, layer-by-layer sequences, and only with constant upgrades to light sources and materials.

SemiconductorSemiconductors are doped silicon crystals whose electrical behaviour is defined by engineered p–n junctions—not inherent material properties. Their utility begins only after quantum physics explains carrier movement and doping makes that movement controllable. They replaced vacuum tubes not because they were 'better' in abstraction, but because they enabled repeatable, scalable, solid-state switching. Nothing about them is automatic, intuitive, or forgiving.
