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.
