LMV716

5 MHz, Low Noise, RRO, Dual Operational Amplifier with

CMOS Input

General Description

The LMV716 is a dual operational amplifier with both low

supply voltage and low supply current, making it ideal for

portable applications. The LMV716 CMOS input stage drives

the I

noise voltage of 12.8 nV/

makes the LMV716 perfect

for applications requiring active filters, transimpedance am-

plifiers, and HDD vibration cancellation circuitry.

Along with great noise sensitivity, small signal applications

will benefit from the large gain bandwidth of 5 MHz coupled

with the minimal supply current of 1.6 mA and a slew rate of

5.8 V/µs.

The LMV716 provides rail-to-rail output swing into heavy

loads. The input common-mode voltage range includes

ground, which is ideal for ground sensing applications.

The LMV716 has a supply voltage spanning 2.7V to 5V and

is offered in an 8-pin MSOP package that functions across

the wide temperature range of −40˚C to 85˚C. This small

package makes it possible to place the LMV716 next to

sensors, thus reducing external noise pickup.
