LMV321, LMV358, LMV324  
General Purpose, Low Voltage, Rail-to-Rail Output Amplifiers  
Features at +2.7V  
Description  
The LMV321 (single), LMV358 (dual), and LMV324 (quad)  
are a low cost, voltage feedback amplifiers that consume only  
80µA of supply current per amplifier. The LMV3XX family  
is designed to operate from 2.7V (±1.35V) to 5.5V (±2.75V)  
supplies. The common mode voltage range extends below the  
negative rail and the output provides rail-to-rail performance.  
• 80µA supply current per channel  
• 1.2MHz gain bandwidth product  
• Output voltage range: 0.01V to 2.69V  
• Input voltage range: -0.25V to +1.5V  
• 1.5V/µs slew rate  
• LMV321 directly replaces other industry standard LMV321  
amplifiers; available in SC70-5 and SOT23-5 packages  
• LMV358 directly replaces other industry standard LMV358  
amplifiers; available in MSOP-8 and SOIC-8 packages  
• LMV324 directly replaces other industry standard LMV324  
amplifiers; available in TSSOP-14 and SOIC-14 packages  
• Fully specified at +2.7V and +5V supplies  
• Operating temperature range: -40°C to +125°C  
The LMV3XX family is designed on a CMOS process and  
provides 1.2MHz of bandwidth and 1.5V/µs of slew rate at a  
low supply voltage of 2.7V. The combination of low power,  
rail-to-rail performance, low voltage operation, and tiny pack-  
age options make the LMV3XX family well suited for use in  
personal electronics equipment such as cellular handsets,  
pagers, PDAs, and other battery powered applications.
