RECOMMENDATIONS FOR ACTUAL DESIGN
To assure proper electrical characteristics, use bypass capacitors with excellent high frequency
characteristics for the power supply and keep them as close as possible to the VA and AG pins.
Connect the AG pin and the DG pin each other as close as possible. Connect to the system
ground with low impedance.
Connect the VA pin and the VD pin as close together as possible and route them to the analog
5 V power supply.
Mount the device directly on the board when mounted on PCBs. Do not use IC sockets. If an
IC socket is 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 V
DD
pin not lower than –0.3 V 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 devices.
Connect analog input pins and digital input pins that are not used to the SG pin and to GND,
respectively.
When the data is written differently from the data defined in the section, Control Data
Description in FUNCTIONAL DESCRIPTION, normal device operation is not guaranteed.
