LMP7711
Precision, 17 MHz, Low Noise, CMOS Input Amplifier
General Description
The LMP7711 is a low noise, low offset, CMOS input, rail-
to-rail output precision amplifier with a high gain bandwidth
and an enable pin. The LMP7711 is part of the LMP™
precision amplifier family and is ideal for a variety of instru-
mentation applications.
Utilizing a CMOS input stage, the LMP7711 achieves an
input bias current of 100 fA, input referred voltage noise of
5.8 nV/
, and an input offset voltage of less than
±150 µV. These features make the LMP7711 a superior
choice for precision applications.
Consuming only 1.15 mA of supply current, the LMP7711
offers a high gain bandwidth of 17 MHz, enabling accurate
amplification at high closed loop gains.
The LMP7711 has a supply voltage range of 1.8V to 5.5V;
which makes this an ideal choice for portable low power
applications with low supply voltage requirements. In order
to reduce the already low power consumption of the
LMP7711, an enable function is available. Once in shut-
down, the LMP7711 draws only 140 nA of supply current.
The LMP7711 is built with National’s advanced VIP50 pro-
cess technology. The LMP7711 is available in a 6-pin
TSOT23 package.
