The LMP201x • LowEnsuredV OverTemperature60µV OS series offers unprecedented accuracy and stability in • LowNoisewithNo1/f35nV/√Hz space-saving miniature packaging, offered at an • HighCMRR 130dB affordable price. This device utilizes patented auto- zero techniques to measure and continually correct • HighPSRR 120dB the input offset error voltage. The result is an • HighAVOL 130dB amplifier which is ultra-stable over time and • WideGain-BandwidthProduct3MHz temperature. It has excellent CMRR and PSRR ratings, and does not exhibit the familiar 1/f voltage • HighSlewRate4V/µs and current noise increase that plagues traditional • LowSupplyCurrent930µA amplifiers. The combination of the LMP201x • Rail-to-RailOutput30mV characteristics makes it a good choice for transducer • NoExternalCapacitorsRequired amplifiers, high gain configurations, ADC buffer amplifiers, DAC I-V conversion, and any other 2.7-V 2 Applications to 5-V application requiring precision and long term stability. • PrecisionInstrumentationAmplifiers Other useful benefits of the LMP201x are rail-to-rail • ThermocoupleAmplifiers output, a low supply current of 930 µA, and wide • StrainGaugeBridgeAmplifier gain-bandwidth product of 3 MHz. These versatile features found in the LMP201x provide high performanceandeaseofuse.
