LMP7707/LMP7708/LMP7709

Precision, CMOS Input, RRIO, Wide Supply Range

Decompensated Amplifiers

General Description

Features

The LMP7707/LMP7708/LMP7709 devices are single, dual,

and quad low offset voltage, rail-to-rail input and output pre-

cision 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 sensor interface and other instrumentation ap-

plications. These decompensated amplifiers are stable at a

gain of 6 and higher.

Unless otherwise noted, typical values at V_S= 5V.

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 LMP7707/LMP7708/LMP7709 ideal for precision

applications. The LMP7707/LMP7708/LMP7709 are built uti-

lizing 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 applica-

tions where conventional CMOS parts cannot operate due to

the voltage conditions.

Applications

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

LMP7707/LMP7708/LMP7709 significantly reduces the CM-

RR glitch commonly associated with rail-to-rail input ampli-

fiers. 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 re-

quiring low supply voltage.

The LMP7707 is offered in the space saving 5-Pin SOT23

package, the LMP7708 is offered in the 8-Pin MSOP and the

quad LMP7709 is offered in the 14-Pin TSSOP package.

These small packages are ideal solutions for area con-

strained PC boards and portable electronics.
