LMC6064IMX

Instrumentation, Op Amps, Buffer Amps Overview

The LMC6064IMX is a precision CMOS quad micropower operational amplifier manufactured by Texas Instruments, which acquired National Semiconductor. It features rail-to-rail input and output capabilities, making it suitable for low-voltage applications. Key electrical parameters include a gain-bandwidth product of 100 kHz, a slew rate of 35 mV/us, and an input offset voltage of 100 uV. The device operates on a supply voltage range of 4.5 V to 15.5 V with a typical operating current of 80 uA per channel. It is housed in a 14-SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer origin carefully, as the component was originally from National Semiconductor but is now produced under Texas Instruments. Confirm the specific suffix 'IMX' corresponds to the SOIC-14 tape-and-reel packaging variant. Ensure compatibility with the required operating temperature range of -40°C to +85°C for your specific design environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both rail-to-rail performance and ultra-low power consumption are critical requirements. It serves as a direct replacement for older National Semiconductor LMC6064 variants. Consider the 100 kHz bandwidth limit; if higher speed is needed, alternative amplifiers must be evaluated. The 14-SOIC package requires appropriate surface-mount assembly processes.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMC6064 series of precision operational amplifiers. It is functionally similar to the LMC6064IM but differs in packaging and manufacturing lineage following the Texas Instruments acquisition of National Semiconductor. The series is designed for applications requiring low power without sacrificing precision.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include the LMC6064IM and LMC6064AIM/NOPB. Verify pinout compatibility and ensure that the replacement part meets the same rail-to-rail and micropower specifications required by the original design.
