... High pass filter reset (HP) The LPR4150AL provides the possibility to reset the optional external high-pass filter by applying a high logic value to the HP pad. This procedure ensures faster response, especially during overload conditions. Moreover, this operation is recommended each time the device is powered. ...

... LPR4150AL electrical connections and external components values Power supply decoupling capacitors (100 nF ceramic or polyester + 10 µF aluminum) should be placed as near as possible to the device (common design practice). The LPR4150AL allows band limiting of the output rate response through the use of an external low-pass filter (recommended) in addition to the embedded low-pass filter (f = 140 Hz) ...
