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 SOIC-14 package
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.
• Fully specified at +2.7V and +5V supplies
• Operating temperature range: -40°C to +125°C
