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.
