DESCRIPTION
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 LMP7711/LMP7712
are part of the LMP™ precision amplifier family and
are ideal for a variety of instrumentation applications.
Utilizing a CMOS input stage, the LMP7711/LMP7712
achieve an input bias current of 100 fA, an input
referred voltage noise of 5.8 nV/√Hz, and an input
offset voltage of less than ±150 μV. These features
make the LMP7711/LMP7712 superior choices for
precision applications.
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 low power applications with low supply
voltage requirements. In order to reduce the already
low power consumption the LMP7711/LMP7712 have
an enable function. Once in shutdown, the
LMP7711/LMP7712 draw only 140 nA of supply
current.
The LMP7711/LMP7712 are built with TI's advanced
VIP50 process technology. The LMP7711 is offered
in a 6-pin SOT package and the LMP7712 is offered
in a 10-pin VSSOP.
