General Description
The LMV341/LMV342/LMV344 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 off set voltage. The PMOS input stage provides the user with ultra-low input bias current of 20fA (typical) and high input impedance.

Features
(Typical 2.7V supply values; unless otherwise noted)
■ Guaranteed 2.7V and 5V specifications
■ Input referred voltage noise (@ 10kHz) 29nV/√Hz
■ Supply current (per amplifier) 100μA
■ Gain bandwidth product 1.0MHz
■ Slew rate 1.0V/μs
■ Shutdown Current (LMV341) 45pA
■ Turn-on time from shutdown (LMV341) 5μs
■ Input bias current 20fA

Applications
■ Cordless/cellular phones
■ Laptops
■ PDAs
■ PCMCIA/Audio
■ Portable/battery-powered electronic equipment
■ Supply current monitoring
■ Battery monitoring
■ Buffer
■ Filter
■ Driver
