Frequently Asked Questions
What is the supply voltage range for the LMV951MK?
The LMV951MK operates from a single supply voltage ranging from 2.7 V to 5.5 V, making it suitable for battery-powered and low-voltage applications where supply headroom is limited.
What does rail-to-rail input and output mean for the LMV951MK?
Rail-to-rail input means the common-mode input voltage can extend to both supply rails, while rail-to-rail output means the output can swing to within millivolts of both the positive and negative supply rails. This maximizes the usable signal dynamic range in low-voltage systems.
What package does the LMV951MK come in?
The LMV951MK is housed in a 6-pin SOT-23 (R-PDSO-G6) surface-mount package, which is compact and ideal for space-constrained PCB designs in portable consumer electronics and wearable devices.
What are typical applications for the LMV951MK operational amplifier?
The LMV951MK is commonly used in sensor signal conditioning, transducer interfaces, audio amplification, active filters, and precision analog front-ends in IoT, medical, and consumer electronics applications requiring low-voltage single-supply operation.
How does the LMV951MK compare to standard op-amps in terms of input bias current?
With a typical input bias current of 0.08 µA and a maximum of 0.085 µA at 25°C, the LMV951MK has significantly lower bias current than general-purpose op-amps, reducing errors when interfacing with high-impedance sources such as pH sensors or capacitive transducers.
