LMV341/LMV342/LMV344
Single with Shutdown/Dual/Quad General Purpose, 2.7V,
Rail-to-Rail Output, 125˚C, Operational Amplifiers
General Description
The LMV341/342/344 are single, dual, and quad low volt-
age, and low power Operational Amplifiers. They are de-
signed specifically for low voltage portable applications.
Other important product characteristics are low input bias
current, rail-to-rail output, and wide temperature range.
The patented class AB turnaround stage significantly re-
duces the noise at higher frequencies, power consumption,
and offset 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
allows the LMV341/342/344 to accommodate a broad range
of extended environment applications. LMV341 expands Na-
tional Semiconductor’s Silicon Dust™ amplifier portfolio of-
fering enhancements in size, speed, and power savings. The
LMV341/342/344 are guaranteed to operate over the voltage
range of 2.7V to 5.0V 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 reduced to 45pA (typical). The LMV341/342/344
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 SC70-6L package, the
LMV342 in space saving MSOP-8 and SOIC-8, and the
LMV344 in TSSOP-14 and SOIC-14. These small package
amplifiers offer an ideal solution for applications requiring
minimum PC board footprint. Applications with area con-
strained PC board requirements include portable electronics
such as cellular handsets and PDAs.
