LMV931 Single/LMV932 Dual/LMV934 Quad

1.8V, RRIO Operational Amplifiers

General Description

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

operational amplifiers. LMV931/LMV932/LMV934 are guar-

anteed to operate from +1.8V to +5.5V supply voltages and

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

input common mode voltage extends 200mV beyond the sup-

plies which enables user enhanced functionality beyond the

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

loaded 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/

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.

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

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

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

and SOIC packages. These small packages are ideal solu-

tions for area constrained PC boards and portable electronics

such as cellular phones and PDAs.
