General Description

Features

The LMP7701 is a single, low offset voltage, rail-to-rail input

and output precision amplifier with a CMOS input stage and

a wide supply voltage range. The LMP7701 is part of the

The guaranteed low offset voltage of less than 200 µV

along with the guaranteed low input bias current of less than

10 pA make the LMP7701 ideal for precision applications.

The LMP7701 is built utilizing VIP50 technology, which al-

lows the combination of a CMOS input stage and a 12V

common mode and supply voltage range. This makes the

LMP7701 a great choice in many applications where con-

ventional CMOS parts cannot operate under the desired

voltage conditions.

Applications

The LMP7701 has 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 dif-

ference between the NMOS and PMOS offsets. The output

of the LMP7701 swings within 40 mV of either rail to maxi-

mize the signal dynamic range in applications requiring low

supply voltage.

The LMP7701 is offered in space saving SOT23-5. This

small package is an ideal solution for area constrained PC

boards and portable electronics.
