range.

The

(max)

LMP7701/LMP7702/LMP7704 are part of the LMP™

precision amplifier family and are ideal for sensor

Input Offset Voltage (LMP7702/LMP7704):

interface and other instrumentation applications.

±220 µV (max)

–

Input Bias Current: ±200 fA

The specified low offset voltage of less than ±200 µV

along with the specified low input bias current of less

many applications where conventional CMOS parts

cannot operate under the desired voltage conditions.

–

Supply Current (LMP7701): 715 µA

–

Supply Current (LMP7702): 1.5 mA

The LMP7701/LMP7702/LMP7704 each have a rail-

Rail-to-Rail Input and Output

the complimentary input stage, thereby reducing the

difference between the NMOS and PMOS offsets.

APPLICATIONS

The

•

High Gain Amplifiers

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.

•

Instrumentation Amplifier

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.
