80μA, 1.0MHz, Micro-Power Rail-to-Rail I/O Op Amps
Description
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.
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 2V
PP
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.
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
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.
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.

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum
Rating condition for extended periods may affect device reliability and lifetime.
Note 2:
The op amp supplies must be established simultaneously, with, or before, the application of any input signals.
Note 3:
The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power supply, the input
current should be limited to less than 10mA.
Note 4:
A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many
amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces
connected to the leads.
