Amplifiers
General 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
interface and other instrumentation applications.
The guaranteed low offset voltage of less than
along with the guaranteed low input bias current of less than
±
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 can-
not operate under the desired voltage conditions.
The LMP7701/LMP7702/LMP7704 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 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 con-
strained PC boards and portable electronics.
