Hello,
I'd like to connect a ADXL193 accelerometer (output : 0V +5V analog) to the ADC of a PIC 12F683 (powered by the same 0V 5V).
However, the PIC 12F683 ADC can accept a source of maximum 10kOhm input resistance and I fear that the ADXL193 won't be able to give enough current.
Therefore I thought about a LM358 Op Amp as a voltage follower (-input to output, +input to the accelerometer, without any resistance nowhere). Is a such voltage follower able to drive the output from 0V to 5V when powered by the same 0V 5V supply?
Also, in the ADXL193 I read "capacitive load drive = 1000pF". Can anyone explain this sentence?
Many thanks for your answers,
