LMV358B-TSR

Overview

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

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific ordering suffix 'TSR' corresponds to the TSSOP-8 package configuration as defined in the manufacturer's order information table. Confirm that the required quantity aligns with the standard tape and reel transport media specification provided in the datasheet documentation.

Selection Notes

Select this component when designing low-voltage systems requiring full rail-to-rail signal swing and high output drive strength. The positive offset voltage characteristic makes it suitable for applications where negative offsets might otherwise cancel small input signals. Ensure the application environment remains within the specified -40°C to +125°C industrial temperature range.

Part Context

This part belongs to the LMV321B/LMV358B/LMV324B series of general-purpose, micro-power CMOS operational amplifiers. The family shares identical electrical characteristics, differing only in the number of channels (single, dual, or quad) and physical package options. The LMV358B specifically provides two independent amplifiers in one package.

Replacement Considerations

The datasheet states the family can serve as plug-in replacements for many commercially available op-amps to reduce power and improve performance. Specific substitute part numbers are not listed in the official documentation.
