LMV342MA/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LMV342MA/NOPB is a dual operational amplifier manufactured by Texas Instruments, formerly National Semiconductor. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device features rail-to-rail output capability and supports an operating temperature range up to 125°C. Key electrical specifications include a gain-bandwidth product of 1 MHz, a slew rate of 1 V/µs, and a maximum input offset voltage of 4 mV. Input bias current is specified at 200 pA, with an operating supply current of 107 µA per channel. The component is housed in an SOIC-8 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Dual-channel architecture providing two independent operational amplifiers within a single integrated circuit.
• Rail-to-rail output stage enabling signal swing close to both supply rails for maximum dynamic range.
• Low power consumption design suitable for battery-operated applications with minimal quiescent current draw.

Instrumentation, Op Amps, Buffer Amps Applications

• Signal conditioning circuits requiring low power and wide common-mode input range
• Active filtering applications in portable electronic devices
• Sensor interface circuits where rail-to-rail output is necessary

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix /NOPB indicates lead-free and RoHS compliance. Ensure the package type matches the required SOIC-8 footprint for PCB layout compatibility. Cross-reference the specific revision level if strict historical manufacturing consistency is required for production runs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual op-amp configuration is needed with rail-to-rail output performance. It is appropriate for designs operating between 2.7 V and 5.5 V where low power consumption is critical. Consider the 1 MHz bandwidth and 1 V/µs slew rate for moderate-speed signal processing tasks. Verify that the 4 mV max offset voltage meets the precision requirements of the specific application circuit.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LMV34x family of general-purpose operational amplifiers. The family includes variants such as the LMV341 (single), LMV342 (dual), and LMV344 (quad). These components share similar electrical characteristics, including low supply current and rail-to-rail output capabilities, designed for cost-sensitive and space-constrained analog applications.
