FEATURES  
DESCRIPTION  
The LMP7717 (single) and the LMP7718 (dual) low  
noise, CMOS input operational amplifiers offer a low  
input voltage noise density of 5.8 nV/Hz while  
consuming only 1.15 mA (LMP7717) of quiescent  
current. The LMP7717/LMP7718 are stable at a gain  
of 10 and have a gain bandwidth (GBW) product of  
88 MHz. The LMP7717/LMP7718 have a supply  
voltage range of 1.8V to 5.5V and can operate from a  
single supply. The LMP7717/LMP7718 each feature a  
rail-to-rail output stage. Both amplifiers are part of the  
LMP™ precision amplifier family and are ideal for a  
variety of instrumentation applications.

Input Offset Voltage: ±150 µV (max)  
Input Referred Voltage Noise: 5.8 nV/Hz  
Input Bias Current: 100 fA  
Gain Bandwidth Product: 88 MHz  
Supply Voltage Range: 1.8V to 5.5V

Rail-to-Rail Output Swing  
The LMP7717 family provides optimal performance in  
low voltage and low noise systems. A CMOS input  
stage, with typical input bias currents in the range of  
a few femto-Amperes, and an input common mode  
voltage range, which includes ground, make the  
LMP7717/LMP7718 ideal for low power sensor  
applications where high speeds are needed.  
@ 10 kLoad: 25 mV from Rail  
@ 2 kLoad: 45 mV from Rail  
Ensured 2.5V and 5.0V Performance  
Total Harmonic Distortion: 0.04% @1 kHz,  
600Ω  
Temperature Range: 40°C to 125°C  
The LMP7717/LMP7718 are manufactured using TI’s  
advanced VIP50 process. The LMP7717 is offered in  
either a 5-Pin SOT-23 or an 8-Pin SOIC package.  
The LMP7718 is offered in either the 8-Pin SOIC or  
the 8-Pin VSSOP.
