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.
