LMP7701/LMP7702/LMP7704

Precision, CMOS Input, RRIO, Wide Supply Range

Amplifiers

General Description

Features

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.

130 dB

The guaranteed low offset voltage of less than 200 µV

along with the guaranteed 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 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.

Applications

n High impedance sensor interface

n Battery powered instrumentation

n High gain amplifiers

n DAC buffer

n Instrumentation amplifier

n Active filters

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.
