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_BIAS current down to 0.6 pA;
this coupled with the low noise voltage of 12.8
nV/√Hz makes the LMV716 perfect for applications
requiring active filters, transimpedance amplifiers,
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 VSSOP 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.
