LMP7704 Datasheet | National Semiconductor

Description The LMP7701/LMP7702/LMP7704 are single, dual, and quad low offset voltage, rail-to-rail input and output precision amplifiers each with CMOS input stage and 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 guaranteed low offset voltage of less than ± 200 µV along with the guaranteed low input bias current of less than ± 1 p A make the LMP7701 ideal for precision applications. The LMP7701/LMP7702/LMP7704 are built utilizing VIP50 technology, which allows the bination of a CMOS input stage and a 12V mon 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 have a rail-to-rail input stage that significantly reduces the CMRR glitch monly associated with rail-to-rail input amplifiers. This is achieved by trimming both sides of the plimentary input stage, thereby reducing the difference between the NMOS and PMOS offsets. The output of the LMP7701/LMP7702/ LMP7704 swings within 40 m V 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 SOT23 package, the LMP7702 is offered in the 8-Pin MSOP, and the quad LMP7704 is offered in the 14-Pin TSSOP package. These small packages are ideal solutions for area constrained PC boards and portable electronics.
