In order to achieve high performance and low noise level it is recommended both AVDD and DVDD
have their own supply voltage regulators and analog ground plane is separated from digital ground
plane near SCP1000. If high performance is not needed, DVDD and AVDD can be supplied from
one regulator. Recommended circuit diagrams for SCP1000 are presented in Table 19 below.
Table 19. SCP1000 recommended circuit diagrams.
In case PD or TRIG pins are not used, in order to decrease the number of connections, they can be
connected to GND, this way the minimum number of connections can be as low as 5 (VDD, GND,
SDA, SCL, DRDY).
Table 20. Recommended capacitor values for SCP1000 circuit diagrams presented in Table 19.
General PWB layout recommendations for SCP1000 products (refer to Table 21):
1. Locate the ceramic SMD filtering capacitors right next to SCP1000 package.
2. Use plane for GND connection.
3. Connect the plane under SCP1000 to AGND.
4. Minimize the power supply/ground loops.
