LMP7711/LMP7712

Single and Dual Precision, 17 MHz, Low Noise, CMOS

Input Amplifiers

General Description

Features

The LMP7711/LMP7712 are single and dual low noise, low

offset, CMOS input, rail-to-rail output precision amplifiers

with a high gain bandwidth product and an enable pin. The

less than 150 µV. These features make the LMP7711/

LMP7712 superior choices for precision applications.

n Operating temperature range

n Rail-to-rail output swing

n Space saving TSOT23 package (LMP7711)

n MSOP-10 package (LMP7712)

Consuming only 1.15 mA of supply current, the LMP7711

offers a high gain bandwidth product of 17 MHz, enabling

accurate amplification at high closed loop gains.

The LMP7711/LMP7712 have a supply voltage range of

1.8V to 5.5V, which makes these ideal choices for portable Applications

low power applications with low supply voltage require-

ments. In order to reduce the already low power consump-

tion the LMP7711/LMP7712 have an enable function. Once

in shutdown, the LMP7711/LMP7712 draw only 140 nA of

supply current.

n Active filters and buffers

n Sensor interface applications

n Transimpedance amplifiers

The LMP7711/LMP7712 are built with National’s advanced

VIP50 process technology. The LMP7711 is offered in a

6-pin TSOT23 package and the LMP7712 is offered in a

10-pin MSOP.
