LMV931 Single / LMV932 Dual / LMV934 Quad

1.8V, RRIO Operational Amplifiers

General Description

Features

The LMV931/LMV932/LMV934 are low voltage, low power

operational amplifiers. LMV931/LMV932/LMV934 are guar-

anteed to operate from +1.8V to +5.0V supply voltages and

have rail-to-rail input and output. LMV931/LMV932/LMV934

input common mode voltage extends 200mV beyond the

supplies which enables user enhanced functionality beyond

the supply voltage range. The output can swing rail-to-rail

unloaded and within 105mV from the rail with 600Ω load at

1.8V supply. The LMV931/LMV932/LMV934 are optimized to

work at 1.8V which make them ideal for portable two-cell

battery powered systems and single cell Li-Ion systems.

LMV931/LMV932/LMV934 exhibit excellent speed-power ra-

tio, achieving 1.4MHz gain bandwidth product at 1.8V supply

voltage with very low supply current. The LMV931/LMV932/ Applications

LMV934 are capable of driving a 600Ω load and up to

1000pF capacitive load with minimal ringing. LMV931/

LMV932/LMV934 have a high DC gain of 101dB, making

them suitable for low frequency applications.

n Consumer computing

n PDAs

n Audio pre-amp

n Portable/battery-powered electronic equipment

n Supply current monitoring

The single LMV931 is offered in space saving SC70-5 and

SOT23-5 packages. The dual LMV932 are in MSOP-8 and

SOIC-8 packages and the quad LMV934 are in TSSOP-14

and SOIC-14 packages. These small packages are ideal

solutions for area constrained PC boards and portable elec-

tronics such as cellular phones and PDAs.
