LMV321A数据手册3PEAK中文资料规格书

描述 Description

LMV321A/358A/324A are CMOS single, dual, andquad op-amps with low offset, stable high frequencyresponse, low power, low supply voltage, andrail-to-rail inputs and outputs. They incorporate3PEAK‟s proprietary and patented designtechniques to achieve best in-class performanceamong all micro-power CMOS amplifiers. 

The LMV321A/358A/324A are unity gain stable withAny Capacitive Load with a Constant 1.0MHzgain-bandwidth product, 0.7V/μs slew rate whileconsuming only 80μA of supply current per amplifier.Analog trim and calibration routine reduces inputoffset voltage tolerance to below 400μV.Adaptivebiasing and dynamic compensation enables theLMV321A /358A/324A to achieve „THD+NOISE‟ for1kHz and 10kHz 2VPP signal at -105dB and -90dB,respectively. Beyond the rails input and rail-to-railoutput characteristics allow the full power-supplyvoltage to be used for signal range. This combination of features makes the LMV321A/358A/324A superior among rail-to-rail input /outputCMOS op amps in its power class. 

TheLMV321A/358A/324A are ideal choices forbattery-powered applications because theyminimize errors due to power supply voltagevariations over the lifetime of the battery andmaintain high CMRR even for a rail-to-rail inputop-amp.The LMV321A/358A/324A can be used ascost-effective plug-in replacements for manycommercially available op amps to reduce powerand improve input/output range and performance.
