LMV341/LMV342/LMV344
Single with Shutdown/Dual/Quad General Purpose, 2.7V,
Rail-to-Rail Output, 125°C, Operational Amplifiers
General Description
The LMV341/LMV342/LMV344 are single, dual, and quad low
voltage, low power Operational Amplifiers. They are designed
specifically for low voltage portable applications. Other im-
portant product characteristics are low input bias current, rail-
to-rail output, and wide temperature range.
The patented class AB turnaround stage significantly reduces
the noise at higher frequencies, power consumption, and off-
set voltage. The PMOS input stage provides the user with
ultra-low input bias current of 20fA (typical) and high input
impedance.
The industrial-plus temperature range of −40°C to 125°C al-
lows the LMV341/LMV342/LMV344 to accommodate a broad
range of extended environment applications. LMV341 ex-
pands National Semiconductor's Silicon Dust ™ amplifier port-
folio offering enhancements in size, speed, and power
savings. The LMV341/LMV342/LMV344 are guaranteed to
operate over the voltage range of 2.7V to 5.5V and all have
rail-to-rail output.
The LMV341 offers a shutdown pin that can be used to disable
the device. Once in shutdown mode, the supply current is re-
duced to 45pA (typical). The LMV341/LMV342/LMV344 have
29nV Voltage Noise at 10KHz, 1MHz GBW, 1.0V/μs Slew
Rate, 0.25mVos, and 0.1μA shutdown current (LMV341.)
The LMV341 is offered in the tiny 6-Pin SC70 package, the
LMV342 in space saving 8-Pin MSOP and SOIC, and the
LMV344 in 14-Pin TSSOP and SOIC. These small package
amplifiers offer an ideal solution for applications requiring
minimum PC board footprint. Applications with area con-
