PRODUCTION DATA
Good power-supply decoupling is important in order to achieve optimum performance. Power supplies must be decoupled close to the device supply pins. For the high-voltage analog supply (HV_AVDD and HV_AVSS), place a 1-µF capacitor between the pins and place 0.1-µF capacitors from each supply to the ground plane. Connect 0.1-µF and 1-µF capacitors in parallel at AVDD to the ground plane. Connect a 1-µF capacitor from DVDD to the ground plane. Connect a 1-µF capacitor from the BYPASS pin to the ground plane. Use multilayer ceramic chip capacitors (MLCCs) that offer low equivalent series resistance (ESR) and equivalent series inductance (ESL) characteristics for power-supply decoupling purposes.
