APPLICATION INFORMATION

Figure 9. MAS6510 configured for I2C bus communication

Note: MAS6510 has an effective ESD clamp protection structure that can be triggered if the VDD rises too fast.

Therefore,

it’s recommended to use a supply decoupling capacitor having a value of 100nF or higher to slow

down the VDD rise time.

Note: The voltage regulator output VREG does not require external capacitor as shown in figure 9. However, if

an output capacitor is wanted to be used for extra filtering the capacitor value should not be higher than 6.8nF.

Figure 9 presents MAS6510 application circuit using I2C bus.

Resolution Improvement

– Averaging

An averaging technique can be used to remove

conversion errors caused by noise and thus improve

measurement resolution. By doing several A/D

conversions and calculating the average result it’s

possible to average out noise. Theoretically the

noise is reduced by a factor

N

where N is the

number

of

averaged

samples.

A/D

converter

nonlinearities cannot be removed by averaging.
