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.
