DESCRIPTION
The LMV341-N/LMV342-N/LMV344-N are single,
dual, and quad low voltage, low power Operational
Amplifiers. They are designed 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
reduces 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-N/LMV342-N/LMV344-N to
accommodate a broad range of extended
environment applications. LMV341-N expands Texas
Instrument's Silicon Dust amplifier portfolio offering
enhancements in size, speed, and power savings.
The LMV341-N/LMV342-N/LMV344-N are specified
to operate over the voltage range of 2.7V to 5.5V and
all have rail-to-rail output.
The LMV341-N 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-N/LMV342-N/LMV344-N have 29nV Voltage
Noise at 10KHz, 1MHz GBW, 1.0V/μs Slew Rate,
0.25mVos, and 0.1μA shutdown current (LMV341-N.)
The LMV341-N is offered in the tiny 6-Pin SC70
package, the LMV342-N in space saving 8-Pin
VSSOP and SOIC, and the LMV344-N in 14-Pin
TSSOP and SOIC. These small package amplifiers
offer an ideal solution for applications requiring
minimum PC board footprint. Applications with area
constrained PC board requirements include portable
electronics such as cellular handsets and PDAs.
