Bypass all supply pins with 1-μF ceramic capacitors. In order to minimize the lead and trace inductance, place the capacitors as close to the supply pins as possible. Where double-sided component mounting is allowed, these capacitors are best placed directly under the package. In addition to power supplies, the device has a reference supply at pins VREFP and VREFN that should also be bypassed. Bypass these pins with at least a 1-μF capacitor as higher value capacitors yield superior low-frequency noise suppression. For best results, choose low-inductance ceramic chip capacitors and place as close as possible to the device pins.

The DVDD power supply operates over the range of 1.75 to 3.6 V. If DVDD is operated at less than 2.25 V, connect the DVDD pin to the BYPAS pin. If DVDD is greater than or equal to 2.25 V, do not connect DVDD to the BYPAS pin. Figure 81 shows this connection.
