... High pass filter reset (HP) The LY503ALH 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 suggested each time the device is powered. ...

... 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 LY503ALH allows band limiting of the output rate response through the use of an external low pass filter (suggested) and/or high pass filter (optional) in addition to the embedded low pass filter (f 4xOUTZ is OUTZ amplified outputs line, internally buffered to ensure low output impedance ...
