LMC6442AIM

Instrumentation, Op Amps, Buffer Amps Overview

The LMC6442AIM is a dual micropower rail-to-rail output single supply operational amplifier. It operates from a supply voltage range of 1.8V to 11V, with electrical characteristics guaranteed at 2.2V, 5V, and 10V. The device features a typical gain-bandwidth product of 9.5 kHz to 10.5 kHz and a slew rate of 2.2 V/ms to 4.1 V/ms. Supply current is typically 1.9 µA for both amplifiers. Input offset voltage is limited to ±8 mV, and input bias current is typically 5 fA. The component is housed in an 8-pin SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the exact package type and reel quantity. Confirm that the component meets RoHS compliance requirements if necessary for your assembly process. Ensure the operating temperature range aligns with your system specifications before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low supply current and rail-to-rail output performance. It is optimized for closed-loop gains greater than plus two or minus one. Unity gain operation requires external compensation circuitry to ensure stability and drive capacitive loads effectively.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMC6442 family of dual micropower operational amplifiers originally developed by National Semiconductor, which is now part of Texas Instruments. The series is designed for battery-powered systems where long service life is critical due to minimal power draw.
