The LPV531 is a very flexible operational amplifier.
A single external resistor enables the system designer to define the quiescent current, gain-bandwidth product, and output short-circuit current capability.
This innovative feature enables system designers to dynamically switch power stages to optimize op amp performance and meet system design requirements.
The LPV531 can be customized for a variety of applications.
It provides the system designer with a dynamic trade-off of the supply current to bandwidth, by adjusting the current derived from me

ability.
The LPV531 is capable of operating from 73 kHz in a time of only 5 μA and up to 4.6 MHz in a fast manner and consuming only 425 μA.
The input offset voltage is relatively independent, so the effect of the chosen power level is not significant.
Using the CMOS input stage, the LPV531 reaches 50 FA and a common-mode input voltage extends from the negative supply rail with a positive supply input bias current of 1.2V.
The LPV531 railway, to the rail Class AB output stage, enables this op amp to provide maximum dynamic range at low supply voltages.
Available in a 6-pin TSOT23 package, the LPV531 is ideal for use in handheld electronics and portable applications.
LPV531 is manufactured using the national advanced VIP50 process.
A fixed supply current/gain bandwidth is available upon request.
