LMV321A/LMV358A/LMV324A  
80μA, 1.0MHz, Micro-Power Rail-to-Rail I/O Op Amps  
Description  
3PEAK  
Features  
LMV321A/358A/324A are CMOS single, dual, and  
quad op-amps with low offset, stable high frequency  
response, low power, low supply voltage, and  
rail-to-rail inputs and outputs. They incorporate  
3PEAK‟s proprietary and patented design  
techniques to achieve best in-class performance  
among all micro-power CMOS amplifiers.  
Upgrade to LMV321/LMV358/LMV324 Family  
Stable 1.0MHz GBWP with Low IQ of Only 80μA  
Typical per Amplifier  
0.7V/μs Slew Rate  
Excellent EMIRR performance: 80dB(1GHz)  
Offset Voltage Tolerance: 400μV Max.  
Offset Voltage Temperature Drift: 1uV/°C  
Input Bias Current: 1pA Typical  
The LMV321A/358A/324A are unity gain stable with  
Any Capacitive Load with a Constant 1.0MHz  
gain-bandwidth product, 0.7V/μs slew rate while  
consuming only 80μA of supply current per amplifier.  
Analog trim and calibration routine reduces input  
offset voltage tolerance to below 400μV. Adaptive  
biasing and dynamic compensation enables the  
LMV321A /358A/324A to achieve „THD+NOISE‟ for  
1kHz and 10kHz 2VPP signal at -105dB and -90dB,  
respectively. Beyond the rails input and rail-to-rail  
output characteristics allow the full power-supply  
voltage to be used for signal range.  
High Output Current: 50mA (1.0V Drop)  
CMRR/PSRR: 95dB/90dB  
Beyond the Rails Input Common-Mode Range  
Outputs Swing to within 6mV Max of each Rail  
No Phase Reversal for Overdriven Inputs  
No Crossover Distortion  
Drives 2kΩ Resistive Loads  
Single +2.1V to +6.0V Supply Voltage Range  
–40°C to 125°C Operation Range  
This combination of features makes the LMV321A  
/358A/324A superior among rail-to-rail input /output  
CMOS op amps in its power class. The  
LMV321A/358A/324A are ideal choices for  
ESD Rating:  
Robust 8KV – HBM, 2KV – CDM  
battery-powered  
applications  
because  
they  
minimize errors due to power supply voltage  
variations over the lifetime of the battery and  
maintain high CMRR even for a rail-to-rail input  
op-amp.  
Green, Popular Type Package  
Applications  
The LMV321A/358A/324A can be used as  
cost-effective plug-in replacements for many  
commercially available op amps to reduce power  
and improve input/output range and performance.
