3 Description
The LMP770x 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 LMP770x 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 LMP770x are built using VIP50
technology, which allows the combination of a CMOS
input stage and a 12-V common-mode and supply
voltage range. This makes the LMP770x ideal for
applications where conventional CMOS parts cannot
operate under the desired voltage conditions.
