FEATURES  
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.

Input Voltage Noise 5.8 nV/√Hz  
Gain Bandwidth Product 17 MHz  
Supply Current (LMP7711) 1.15 mA  
Supply Current (LMP7712) 1.30 mA  
Supply Voltage Range 1.8V to 5.5V  
THD+N @ f = 1 kHz 0.001%  
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.  
Operating Temperature Range −40°C to 125°C  
Rail-to-rail Output Swing  
Space Saving SOT Package (LMP7711)  
10-pin VSSOP Package (LMP7712)  
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.
