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 LPR403AL 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
Hz).
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 a non-amplified output is used (OUTX/OUTZ), it is recommended to set pin 5
and 16 to a fixed reference voltage (Vref).
The LPR403AL 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
LPR403AL electrical connections and external component values
Figure
