The 0.002 pA input bias current is the standout: it lets you buffer signals from high-impedance sources like photodiode transimpedance amplifiers or pH probe interfaces without adding measurable offset drift. ## Supply current that matters for battery life Total supply current for all four amplifiers is 52 µA — about 13 µA per channel. In a battery-powered sensor node running from two alkaline cells, that current draw is negligible compared to the microcontroller or radio. ## Industrial temperature grade and through-hole package The 14-DIP package (0.300\" width) is through-hole — easy to hand-solder, socket, or rework, but it takes up board area that a surface-mount SOIC or TSSOP would save. If your design is already on a mixed-technology board with other DIP parts, this package is a natural fit. If you are space-constrained, consider the surface-mount LMC6044AIM or a smaller-package alternative. ## Active lifecycle, but RoHS non-compliant For new designs targeting RoHS compliance (EU Directive 2011/65/EU), you will need an exemption or a RoHS-compliant alternate.","metaTitle":"LMC6044IN CMOS Quad Op-Amp, 100 kHz GBW, Rail-to-Rail Output","metaDescription":"LMC6044IN from Texas Instruments: quad CMOS op-amp with 100 kHz GBW, 0.02 V/µs slew rate, 0.002 pA input bias, rail-to-rail output.

The OPA4374 is better for higher-speed signal chains where the LMC6044IN's 52 µA total supply is the priority. Pin compatibility is not guaranteed; verify the footprint for your board."},{"question":"What is the gain bandwidth of LMC6044IN?","answer":"The gain bandwidth product is 100 kHz. This sets the usable frequency range for closed-loop gain: at a gain of 100, the bandwidth drops to about 1 kHz. It is intended for DC and low-frequency applications, not audio or video amplification."},{"question":"Does LMC6044IN have rail-to-rail output?","answer":"Yes, the output type is push-pull, rail-to-rail. The output swings within a few millivolts of the positive and negative supply rails, maximizing dynamic range in single-supply designs."},{"question":"What is the LMC6044IN slew rate?","answer":"The slew rate is 0.02 V/µs. This is a very slow rate — the output takes about 50 µs to swing 1 V. It is suitable for DC and low-frequency signals, but it will distort fast edges or high-frequency waveforms."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMC6044IN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMC6044IN when reusing this data.
