For most applications, a single 0.1 µF capacitor, CDC, will adequately decouple the accelerometer from noise on the power supply. However in some cases, particularly where noise is pre-sent at the 140 kHz internal clock frequency (or any harmonic thereof), noise on the supply may cause interference on the ADXL103/ADXL203 output. If additional decoupling is needed, a 100 Ω (or smaller) resistor or ferrite beads may be inserted in the supply line of the ADXL103/ADXL203. Additionally, a larger bulk bypass capacitor (in the 1 µF to 22 µF range) may be added in parallel to CDC.
