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, 0.9

V/μs slew rate while

consuming only 40

μA 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.

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.
