FEATURES

DESCRIPTION

The LMP7707/LMP7708/LMP7709 devices are

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

input and output precision amplifiers which each have

a CMOS input stage and a wide supply voltage

range. The LMP7707/LMP7708/LMP7709 are part of

the LMP™ precision amplifier family and are ideal for

applications. These decompensated amplifiers are

stable at a gain of 6 and higher.

Input Voltage Noise 9 nV/√Hz

CMRR 130 dB

The ensured low offset voltage of less than ±200 µV

along with the ensured low input bias current of less

than ±1 pA make the LMP7707/LMP7708/LMP7709

Open Loop Gain 130 dB

Temperature Range −40°C to 125°C

Gain Bandwidth Product (A_V=10) 14 MHz

Stable at a Gain of 10 or Higher

Supply Current (LMP7707) 715 µA

Supply Current (LMP7708) 1.5 mA

Supply Current (LMP7709) 2.9 mA

Supply Voltage Range 2.7V to 12V

applications.

The

LMP7707/LMP7708/LMP7709 are built utilizing VIP50

technology, which allows the combination of a CMOS

input stage and a supply voltage range of 12V with

rail-to-rail common mode voltage capability. The

LMP7707/LMP7708/LMP7709 are the perfect choice

in many applications where conventional CMOS parts

cannot operate due to the voltage conditions.

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

each

the

LMP7707/LMP7708/LMP7709

APPLICATIONS

significantly reduces the CMRR glitch commonly

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

of the complimentary input stage have been trimmed,

thereby reducing the difference between the NMOS

and PMOS offsets. The output swings within 40 mV

of either rail to maximize the signal dynamic range in

applications requiring low supply voltage.

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

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.
