3 Description
The LMV34x-N devices 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 20 fA (typical) and high input impedance.
The industrial-plus temperature range of −40°C to
125°C allows the LMV34x-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 LMV34x-N devices
are specified to operate over the voltage range of
2.7 V to 5.5 V 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 45 pA (typical). The
LMV34x-N devices have 29-nV voltage noise at 10
KHz, 1 MHz GBW, 1-V/µs slew rate, 0.25 mVos, and
0.1-µA 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 packages, and the LMV344-N in
14-pin TSSOP and SOIC packages. These small
package amplifiers offer an ideal solution for
applications requiring minimum PCB footprint.
Applications with area constrained PCB requirements
include portable electronics such as cellular handsets
and PDAs.
