DESCRIPTION
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.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
