88 MHz, Precision, Low Noise, 1.8V CMOS Input, Decompensated Operational Amplifier - LMP7718

LMP7718 (ACTIVE)

88 MHz, Precision, Low Noise, 1.8V CMOS Input, Decompensated Operational Amplifier

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.
