FEATURES

DESCRIPTION

The

LMP7707/LMP7708/LMP7709

devices

are

23

•

Unless Otherwise Noted, Typical Values at

single, dual, and quad low offset voltage, rail-to-rail

input and output precision amplifiers which each have

•

Input Offset Voltage (LMP7707) ±200 µV (Max)

a CMOS input stage and a wide supply voltage

•

Input Offset Voltage (LMP7708/LMP7709)

range. The LMP7707/LMP7708/LMP7709 are part of

the LMP™ precision amplifier family and are ideal for

±220 µV (Max)

sensor

interface

and

other

instrumentation

•

Input Bias Current ±200 fA

applications. These decompensated amplifiers are

•

Input Voltage Noise 9 nV/

√Hz

stable at a gain of 6 and higher.

•

CMRR 130 dB

The ensured low offset voltage of less than ±200 µV

•

Open Loop Gain 130 dB

along with the ensured low input bias current of less

than ±1 pA make the LMP7707/LMP7708/LMP7709

•

Temperature Range

−40°C to 125°C

ideal

for

precision

applications.

The

•

LMP7707/LMP7708/LMP7709 are built utilizing VIP50

•

Stable at a Gain of 10 or Higher

technology, which allows the combination of a CMOS

•

Supply Current (LMP7707) 715 µA

input stage and a supply voltage range of 12V with

rail-to-rail common mode voltage capability. The

•

Supply Current (LMP7708) 1.5 mA

LMP7707/LMP7708/LMP7709 are the perfect choice

•

Supply Current (LMP7709) 2.9 mA

in many applications where conventional CMOS parts

•

Supply Voltage Range 2.7V to 12V

cannot operate due to the voltage conditions.

•

Rail-to-Rail Input and Output

The unique design of the rail-to-rail input stage of

each

of

the

LMP7707/LMP7708/LMP7709

APPLICATIONS

significantly reduces the CMRR glitch commonly

associated with rail-to-rail input amplifiers. Both sides

High Impedance Sensor Interface

of the complimentary input stage have been trimmed,

•

Battery Powered Instrumentation

thereby reducing the difference between the NMOS

•

High Gain Amplifiers

and PMOS offsets. The output swings within 40 mV

of either rail to maximize the signal dynamic range in

•

DAC Buffer

applications requiring low supply voltage.

•

Instrumentation Amplifier

The LMP7707 is offered in the space-saving 5-pin

•

Active Filters

SOT-23 and 8-pin SOIC packages, the LMP7708 is

offered

in

the

8-pin

VSSOP

and

8-pin

SOIC

packages, and the quad LMP7709 is offered in the

14-pin TSSOP and 14-pin SOIC packages. These

small

packages

are

ideal

solutions

for

area

constrained PC boards and portable electronics.
