illustrate
The LMP7701/LMP7702/LMP7704 are single, dual and quad low offset voltages, rail-to-rail inputs and outputs with CMOS precision amplifier input stages and a wide supply voltage range each. The LMP7701/LMP7702/LMP7704 are part of the LMP family of high precision amplifiers, ideal for sensor interfaces and other instrumentation applications.
Guaranteed low offset voltage of less than ± 200 μV less together ensure low input bias of more than ± 1 pA makes the LMP7701 ideal current for high accuracy applications. The LMP7701/LMP7702/LMP7704 are built to utilize VIP50 technology, which allows a CMOS input stage combined with a 12V common-mode and supply voltage range. This makes the LMP7701/LMP7702/LMP7704 a great choice for traditional CMOS components in many applications where traditional CMOS components cannot operate at the required voltages.
The LMP7701/LMP7702/LMP7704 have a rail-to-rail input stage that greatly reduces CMRR glitches and typically has rail-to-rail input amplifiers. This is done by trimming the free input to both sides of the stage, thereby reducing the difference between NMOS and PMOS offset. The LMP7701/LMP7702/LMP7704 fluctuating output within either railway is 40 millivolts to maximize signal dynamic range in applications requiring low supply voltages.
The LMP7701 is available in a 5-pin SOT23 package and an 8-pin SOIC package. The LMP7702 is available in 8-pin SOIC and 8-pin MSOP packages. The LMP7704 is available in 14-pin SOIC and 14-pin TSSOP packages. These small packages of printed circuit boards are an ideal solution for area constraints and portable electronics.
