there isn't any information about an external RC-filter in the datasheet for ADXL78 but only Capacitive Load Drive (1000pF) in the Specification table is shown.
Should one place external RC-filter (or only C) and what about R,C values?
Or may be internal Bessel filter doesn't require external RC filter?
Is the output capacity of the ADXL78 the same as for the ADXL001? (There was already post about the ADXL001 output here)
