LMV358B-SR

Instrumentation, Op Amps, Buffer Amps Overview

The LMV358B-SR is a dual-channel CMOS operational amplifier manufactured by 3PEAK. It operates on a single supply voltage ranging from 2.5V to 5.5V with a quiescent current of 80μA per channel. The device features rail-to-rail input and output capabilities, allowing the common-mode input voltage range to extend 100mV beyond the power rails. Key electrical specifications include a gain-bandwidth product of 1MHz, a slew rate of 0.7V/μs, and an input offset voltage typically between +1mV and +4mV. It supports an operating temperature range from -40°C to +125°C and is housed in an SOP-8 package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output capability with extended common-mode voltage range
• Low power consumption with 80μA quiescent current per channel
• Positive offset voltage design (+1mV to +4mV) to prevent signal cancellation
• High output drive capability supporting heavy capacitive loads

Instrumentation, Op Amps, Buffer Amps Applications

• Active filters and ASIC input or output amplifiers
• Sensor interfaces for smoke, gas, and environmental monitoring
• Portable instruments and mobile devices
• Motor control and portable audio amplification

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against the manufacturer's official order information table to confirm the exact package type and tape-and-reel quantity. Ensure the component marking matches the datasheet requirements for date code identification. Confirm that the intended application environment falls within the specified absolute maximum ratings and thermal limits to maintain device reliability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing low-voltage systems requiring full input and output swing near the supply rails. The positive offset voltage characteristic makes it suitable for applications where small signals must be amplified without being cancelled by negative offset errors. Consider its high output drive capability if driving heavy capacitive loads such as LCD displays or long cables.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMV321B/LMV358B/LMV324B family of general-purpose, micro-power CMOS op-amps. While the LMV321B offers a single channel and the LMV324B provides four channels, the LMV358B specifically integrates two independent amplifiers in one package. All variants share identical electrical characteristics and pinout configurations relative to their channel count.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The datasheet states these op-amps can serve as plug-in replacements for many commercially available op-amps to reduce power and improve performance. Verify pin compatibility and ensure the substitute device meets the required rail-to-rail input/output specifications and supply voltage range.
