LMV321TP/LMV358TP/LMV324TP
40μA, 1.27MHz, Micro-Power Rail-to-Rail I/O Op Amps
Features
Description
Upgrade to LMV321/LMV358/LMV324 Family
LMV321TP/358TP/324TP are CMOS single, dual,
Stable 1.27MHz GBWP with Low IQ of Only 40μA
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.
Typical per Amplifier
0.9V/μs Slew Rate
Unity Gain Stable for ANY CAPACITIVE Load
Offset Voltage: 3.5mV Maximum
Offset Voltage Temperature Drift: 0.6uV/°C
Input Bias Current: 1pA Typical
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 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.
THD+Noise: -105dB at 1kHz, -90dB at 10kHz
CMRR/PSRR: 110dB/102dB
Beyond the Rails Input Common-Mode Range
Outputs Swing to within 5mV Typical 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 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
ESD Rating:
Robust 8KV – HBM, 2KV – CDM and 500V – MM
battery-powered
applications
because
they
Green, Popular Type Package
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.
Applications
Active Filters, ASIC Input or Output Amplifier
Sensor Interface
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.
