RECOMMENDATIONS FOR ACTUAL DESIGN
• To assure specified electrical characteristics, use bypass capacitors with excellent high frequency characteristics
for the power supply and keep them as close as possible to the device pins.
• Connect the AG pin and DG pin each other as closely as possible. Connect to the system ground with low
impedance.
• Connect the VDDA pin to the VDD pin as closely as possible and connect them to the analog power supply at a
low impedance.
• Directly mount this device onto the printed circuit board without using an IC socket. Unless unavoidable, use
short lead type socket.
• When mounted on a frame, use electromagnetic shielding, if any electromagnetic emission sources such as
power supply transformers surround the device.
• Keep the voltage on the VDD pin not lower than –0.3 V even instantaneously to avoid latch-up phenomenon when
turning the power on.
• Use a low noise power supply (having low level high frequency spike noise or pulse noise) to avoid erroneous
operation and the degradation of the characteristics of these device.
