The LMP7701/LMP7702/LMP7704 are single, dual, and quad low offset voltage, rail-to-rail input and output precision amplifiers each with a CMOS input stage and a wide supply voltage range. The LMP7701/LMP7702/LMP7704 are part of the LMP precision amplifier family and are ideal for sensor interface and other instrumentation applications.
The specified low offset voltage of less than ±200 µV along with the specified low input bias current of less than ±1 pA make the LMP7701 ideal for precision applications. The LMP7701/LMP7702/LMP7704 are built utilizing VIP50 technology, which allows the combination of a CMOS input stage and a 12V common mode and supply voltage range. This makes the LMP7701/LMP7702/LMP7704 great choices in many applications where conventional CMOS parts cannot operate under the desired voltage conditions.
The LMP7701/LMP7702/LMP7704 each have a rail-to-rail input stage that significantly reduces the CMRR glitch commonly associated with rail-to-rail input amplifiers. This is achieved by trimming both sides of the complimentary input stage, thereby reducing the difference between the NMOS and PMOS offsets. The output of the LMP7701/LMP7702/LMP7704 swings within 40 mV of either rail to maximize the signal dynamic range in applications requiring low supply voltage.
The LMP7701 is offered in the space saving 5-Pin SOT-23 and 8-Pin SOIC package. The LMP7702 is offered in the 8-Pin SOIC and 8-Pin VSSOP package. The quad LMP7704 is offered in the 14-Pin SOIC and 14-Pin TSSOP package. These small packages are ideal solutions for area constrained PC boards and portable electronics.
