The LMP7704MA/NOPB (购买请点击)are single, dual, andquad low offset voltage, rail-to-rail input and output precisionamplifiers each with CMOS input wide supplyvoltage range. The are part ofhe LMP™ precision amplifier family and are ideal for sensorinterface and other instrumentation applications.
The guaranteed low offset voltage of less than ±200 μValong with the guaranteed low input bias current of less than±1 pA make theideal for precision applications.The LMP7704MA/NOPB (购买请点击) are built utilizing VIP50technology, which allows the combination of a CMOS inputstage and a 12V common mode and supply voltage range.
This makes the LMP7704MA/NOPB (购买请点击) great choicesin many applications where conventional CMOS parts cannotoperate under the desired voltage conditions.
The LMP7704MA/NOPB (购买请点击) have a rail-to-rail inputstage that significantly reduces the CMRR glitch commonlyassociated with rail-to-rail input amplifiers. This is achievedby trimming both sides of the complimentary input stage,thereby reducing the difference between the NMOS andPMOS offsets. The output of the swings within 40 mV of either rail to maximize thesignal dynamic range in applications requiring low supplyvoltage.
