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 LPR430AL allows band limiting the output rate response through the use of an external
low-pass filter (recommended) in addition to the embedded low-pass filter (f
4xOUTX and 4xOUTY are, respectively, OUTX and OUTY amplified output lines, internally
buffered to ensure low output impedance.
If external low-pass filtering is not applied, it is mandatory to short-circuit pin 1 to pin 5 and
pin 16 to pin 20, respectively, when amplified outputs are used.
When only non-amplified output is used (OUTX/OUTY), it is recommended to set pin 5 and
16 to fixed reference voltage (Vref).
The LPR430AL IC includes a PLL (phase-locked loop) circuit to synchronize driving and
sensing interfaces. Capacitors and resistors must be added at the FILTVDD and VCONT
pins (as shown in
LPR430AL electrical connections and external component values
