To assure 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 close as possible. Connect to the
system ground with low impedance.
unavoidable, use the short lead type socket.
When mounted on a frame, use electro-magnetic shielding, if any electro-magnetic
wave source such as power supply transformers surround the device.
Keep the voltage on the VDD pin not lower than -0.3V even instantaneously to
avoid latch-up phenomenon when turning the power on.
Use a low noise (particularly, low level type of high frequency spike noise or pulse
noise) power supply to avoid erroneous operation and the degradation of the
characteristics of these device.
