特性特点

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 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 hoices 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.
