Product details

Quad CMOS op-amp for precision, high-impedance signal chains

The four amplifiers share a single 14-SOIC package, making it a space-efficient choice for multi-channel sensor conditioning, photodiode amplifiers, data acquisition front-ends, and battery-powered instrumentation where every microamp of bias current matters.

Slew rate and bandwidth — what they mean for signal fidelity

For a 5 V peak-to-peak output step, the slew rate limits the full-swing risetime to about 3.8 µs. That is fast enough for 10 kHz sine waves at full amplitude and for multiplexed data-acquisition channels scanning at tens of kilohertz. If your application requires faster settling — say, driving a 100 kHz signal at 10 V p-p — a higher-slew-rate part like the OPA4374 (5 V/µs) may be a better fit. The 1.5 MHz GBW also means closed-loop gain up to 100 at 15 kHz is stable with typical compensation.

The junction temperature rating (TJ) means the die temperature — not just ambient — is the limit; in a still-air environment at 85°C ambient, the 2.6 mA supply current per channel (10.4 mA total) produces negligible self-heating, so the full temperature range is usable without derating.

Frequently asked questions

Where can I buy LMC6484IMX with stock?

The LMC6484IMX is available through independent distribution. Submit an RFQ to confirm current availability and pricing for your required quantity. Stock levels and lead times are confirmed at quote time.

Is LMC6484IMX rail-to-rail?

The output is rail-to-rail, which maximizes dynamic range in single-supply circuits. The input common-mode range is not rail-to-rail — it extends to the negative rail but stops about 1 V below the positive rail, so high-side sensing at low supply voltages requires attention.

When sourcing LMC6484IMX, what is the closest functional second-source — OPA4374AIPWT?

It is not a pin-compatible drop-in — the LMC6484IMX operates up to 15.5 V and has significantly lower bias current.
