LMV796/LMV797

17 MHz, Low Noise, CMOS Input, 1.8V Operational

Amplifiers

General Description

Features

(Typical 5V supply, unless otherwise noted)

n Input referred voltage noise

n Input bias current

The LMV796 (Single) and the LMV797 (Dual) low noise,

CMOS input operational amplifiers offer a low input voltage

5.8 nV/

noise density of 5.8 nV/

while consuming only 1.15 mA

17 MHz

(LMV796) of quiescent current. The LMV796 and LMV797

are unity gain stable op amps and have gain bandwidth of 17

MHz. The LMV796/ LMV797 have a supply voltage range of

1.8V to 5.5V and can operate from a single supply. The

LMV796/LMV797 each feature a rail-to-rail output stage ca-

pable of driving a 600Ω load and sourcing as much as 60 mA

of current.

The LMV796 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 femtoAm-

peres, and an input common mode voltage range, which

includes ground, make the LMV796 and the LMV797 ideal

for low power sensor applications.

n Guaranteed 2.5V and 5.0V performance

n Total harmonic distortion

n Temperature range

−40˚C to 125˚C

Applications

The LMV796/LMV797 are manufactured using National’s

advanced VIP50 process and are offered in a 5-pin SOT23

and an 8-pin MSOP package respectively.

n Photodiode amplifiers

n Active filters and buffers

n Low noise signal processing

n Medical instrumentation

n Sensor interface applications
