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.
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.
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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
