Description
LMV321TP/358TP/324TP 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 LMV321TP/358TP/324TP are unity gain stable
with Any Capacitive Load with a Constant 1.27MHz
gain-bandwidth product, 0.9V/μs slew rate while
consuming only 40μA of supply current per amplifier.
Analog trim and calibration routine reduces input
offset voltage to below 3.5mV. Adaptive biasing and
dynamic compensation enables the LMV321TP
/358TP/324TP 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 LMV321TP
/358TP/324TP superior among rail-to-rail input
/output CMOS op amps in its power class. The
LMV321TP/358TP/324TP 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 LMV321TP/358TP/324TP 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.
Applications
Active Filters, ASIC Input or Output Amplifier
Sensor Interface
Smoke/Gas/Environment Sensors
Portable Instruments and Mobile Device
Audio Output
PCMCIA Cards
Battery or Solar Powered Systems
Medical Equipment

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 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 3:
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.
