Produktdetails

LMC6042AIMX/NOPB – TI Dual CMOS Micropower Operational Amplifier

LMC6042AIMX/NOPB is a Texas Instruments dual CMOS micropower operational amplifier designed for ultra-low-power analog signal conditioning and high-impedance sensing applications. With 100kHz gain-bandwidth product, 10µA/amp typical supply current, 2fA typical input current, input common-mode range including ground and SOIC-8 package, it is suitable for battery monitoring, photodiode preamplifiers, pH probe buffers, portable instruments and low-leakage sensor interfaces.

PackageD / SOIC-8

Engineering note: Verify the latest TI datasheet, input leakage requirement, PCB guard-ring layout, output swing, supply voltage and system accuracy target before production approval.

Component Overview

LMC6042AIMX/NOPB belongs to the TI LMC604x family of CMOS dual micropower operational amplifiers. It is intended for circuits that require very low input current, low supply current and analog signal amplification in single-supply, battery-powered or high-impedance systems.

TomatoElec view: LMC6042AIMX/NOPB is useful when a design needs a low-leakage, low-power dual op amp rather than a high-speed amplifier. Its value comes from 2fA typical input current, 10µA/amp supply current, rail-to-rail output swing and stable use in precision sensing and portable analog circuits.

Circuit Function & Design Role

High-Impedance Signal Buffering

Buffers weak sensor signals where input leakage current must be extremely low.

Battery-Powered Analog Design

The low supply current helps extend battery life in portable and always-on monitoring systems.

Low-Leakage Sensing

Suitable for photodiode, pH probe, electrometer-style and other high-impedance input circuits.

Dual-Channel Integration

Two amplifier channels in one SOIC-8 package help simplify filtering, buffering and instrumentation circuits.

Design reminder: For femtoamp-level input circuits, PCB leakage can dominate the error budget. Use clean PCB layout, guard rings, high-impedance routing practice and careful contamination control.

Application Scenarios

Battery Monitoring

Used in low-power monitoring circuits where long operating life and low supply current are important.

Photodiode & IR Preamplifiers

Suitable for light-sensing front ends that require very low input current and high input impedance.

pH Probe Buffers

Useful for chemical sensing and probe buffering where the signal source impedance is extremely high.

Portable Instruments

Applicable to portable analytic instruments, electrometers, barcode readers and low-leakage sensing systems.

TomatoElec Quality & Supply Notes

As an in-stock independent distributor and electronic components supplier, TomatoElec supports LMC6042AIMX/NOPB sourcing for engineering samples, production replenishment, urgent replacement and BOM purchasing. For micropower CMOS op amps, correct package, manufacturer marking, reel condition and original sourcing are important because the device affects leakage performance, analog accuracy and long-term system reliability.

Original component sourcing: support sourcing of original Texas Instruments operational amplifier ICs.
Inventory support: help confirm available stock, package condition, date code and shipment schedule.
Package verification: confirm the D / SOIC-8 package and tape-and-reel carrier before shipment.
BOM matching: verify channel count, supply range, input current, package, pinout and temperature requirements before approving any substitute.

Replacement & BOM Matching Guidance

LMC6042AIMX/NOPB should not be replaced only by matching the dual op amp category. Engineers should compare input bias current, input leakage, supply current, GBW, slew rate, input common-mode range, output swing, offset voltage, package, pinout and PCB leakage requirements.

Selection tip: A faster or cheaper dual op amp may not be suitable if it has much higher input bias current or supply current. For pH probes, photodiodes and high-impedance sensors, leakage and PCB layout often matter more than bandwidth.

FAQ

What is LMC6042AIMX/NOPB used for?

It is used for battery monitoring, power conditioning, photodiode and infrared detector preamplifiers, pH probe buffers, portable instruments, electrometers and low-leakage signal conditioning.

Is LMC6042AIMX/NOPB a dual op amp?

Yes. LMC6042AIMX/NOPB is a dual CMOS micropower operational amplifier in an 8-pin SOIC package.

Why is the input current important?

The typical 2fA input current helps reduce measurement error in high-impedance sensor circuits, such as photodiode, pH probe and electrometer-style applications.

Can TomatoElec support LMC6042AIMX/NOPB sourcing?

TomatoElec can support LMC6042AIMX/NOPB inquiry, inventory confirmation, BOM sourcing and shipment coordination.

Final Selection Summary

LMC6042AIMX/NOPB is a dual CMOS micropower operational amplifier for designs requiring very low input current, low supply current, rail-to-rail output swing and compact SOIC-8 packaging.

TomatoElec recommendation: Use LMC6042AIMX/NOPB when the BOM requires Texas Instruments dual CMOS micropower op amp performance, ultra-low input current, low-power single-supply operation and D / SOIC-8 packaging.
