current, rail-to-rail output, and wide temperature range.

n Guaranteed 2.7V and 5V specifications

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.

LMV341/342/344 are guaranteed to operate over the voltage

range of 2.7V to 5.0V and all have rail-to-rail output.

Applications

n Cordless/cellular phones

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
