3 Description

The LMV93x-N family (LMV931-N single, LMV932-N

dual and LMV934-N quad) are low-voltage, lowpower

operational amplifiers. The LMV93x-N family

operates from 1.8-V to 5.5-V supply voltages and

have rail-to-rail input and output. The input commonmode

voltage extends 200 mV beyond the supplies

which enables user enhanced functionality beyond

the supply voltage range. The output can swing railto-

rail unloaded and within 105 mV from the rail with

600-Ω load at 1.8-V supply. The LMV93x-N devices

are optimized to work at 1.8 V, which make them

ideal for portable two-cell, battery-powered systems

and single-cell Li-Ion systems.

LMV93x-N devices exhibit an excellent speed-power

ratio, achieving 1.4-MHz gain bandwidth product at

1.8-V supply voltage with very low supply current.

The LMV93x-N devices can drive a 600-Ω load and

up to 1000-pF capacitive load with minimal ringing.

These devices also have a high DC gain of 101 dB,

making them suitable for low-frequency applications.

The single LMV93x-N is offered in space-saving 5-pin

SC70 and SOT-23 packages. The dual LMV932-N

are in 8-pin VSSOP and SOIC packages and the

quad LMV934-N are in 14-pin TSSOP and SOIC

packages. These small packages are ideal solutions

for area constrained PC boards and portable

electronics such as mobile phones and tablets.
