RECOMMENDATIONS FOR ACTUAL DESIGN
• To assure proper electrical characteristics, use bypass capacitors with excellent high frequency
• Connect the AG pin and the DG pin each other as close as possible. Connect to the system
• Connect the VA pin and the VD pin as close together as possible and route them to the analog
• Mount the device directly on the board when mounted on PCBs. Do not use IC sockets. If an
• When mounted on a frame, use electro-magnetic shielding, if any electro-magnetic wave
• Keep the voltage on the V
• Use a low noise (particularly, low level type of high frequency spike noise or pulse noise) power
• Connect analog input pins and digital input pins that are not used to the SG pin and to GND,
• When the data is written differently from the data defined in the section, Control Data
