LMC6572AIM/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LMC6572AIM/NOPB is a dual low voltage operational amplifier manufactured by Texas Instruments, formerly National Semiconductor. It features rail-to-rail input and output capabilities with an input offset voltage of 3.5 mV and input bias current of 20 fA. The device operates on a single supply from 2.7 V to 3 V, consuming 80 uA per channel. It provides 6 mA output current per channel, 63 dB CMRR, and 67 dB PSRR. Packaged in an 8-SOIC format, it functions within a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation carefully as the component originates from National Semiconductor but is now distributed under Texas Instruments branding. Confirm the specific suffix matches the required package and temperature grade. Check availability status as distribution channels may list this part as discontinued or obsolete depending on the region.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits requiring rail-to-rail performance at very low supply voltages. Ensure the application stays within the specified 2.7 V to 3 V operating range. Consider the 80 uA quiescent current for power-sensitive designs. Verify that the 6 mA drive capability meets load requirements without exceeding thermal limits in the SOIC-8 package.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LMC6572 series of precision amplifiers. It represents the transition period where National Semiconductor products were integrated into Texas Instruments' portfolio. The NOPB suffix indicates lead-free construction compliant with environmental standards. It serves as a dual-channel variant within the broader family of low-power CMOS operational amplifiers.
