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.
