Scaling ADXL50 accelerometer output - The ADXL50 accelerometer provides as its
output a voltage level which varies in proportion to the amount of acceleration
experienced along its sensitive axis. It is calibrated such that under no acceleration the
output will be 1.8 volts. Furthermore, an acceleration of 50g (where 1g is the
acceleration due to gravity) will cause a voltage swing.... [Tim Stilson]

Switched capacitor IC controls feedback loop - 02/17/00 EDN -Design IdeasYou can
implement a simple control loop with a constant setpoint over a wide range of control by
using a switched-capacitor filter. The circuit controls motor speed over 1 to 200 Hz or 60
to 12,000 rpm. In Figu EDN is migrating links. This link is not verified. Search the
