Technical Note
●Operation Notes
(1) The electrical characteristic and data on graphs for this datasheet, are typically evaluated value, and not guaranteed.
(2) We suppose that application circuits are recommendable, but please make sufficient check for characteristics with the
actual application. In case that value of external component for this LSI is changed, please check characteristic, not only
static but also transient.
(3) About absolute maximum ratings
If operation condition is over the absolute maximum ratings, supply voltage or other operation range, LSI will be broken.
Please don't apply any voltage or temperature over the absolute maximum ratings. If application have possibilities of
become over the absolute maximum ratings, please take safety measures by using fuse and so on. Not to over absolute
maximum ratings of LSI.
(4) GND voltage
Please keep GND voltage lowest of any other terminal of this LSI. Please confirm that other terminal voltages are not
lower than GND.
(5) Thermal design
Please making a thermal design that allows for a sufficient margin in light of the power dissipation in actual operating
condition.
(6) About terminals short and wrong mounting
Please pay full attention to the LSI direction and displacement when mounting LSI on PCB. If you assemble them by
mistake and electrify it, LSI might be destroyed. And it is happen to short among LSI terminals or terminals and power
supply, by foreign substance.
(7) About operation in strong electromagnetic field
If you use it in strong electromagnetic field, please evaluate fully as there is a possibility of malfunction.
(8) Place a bypass capacitor as close as possible between each power supply terminal and ground in order to prevent
deterioration of the D/A conversion accuracy due to ripple and noise signals from power supply or GND.
(9) A capacitor should be placed between the analog output and ground in order to eliminate noise.
A capacitance up to 100pF is recommended (including the capacitance of the wire).
(10) This IC is selectable to decode the 10bit DI data pattern using either LSB first or MSB first, depending on the conditions
of the REVERSE terminal. Therefore the reverse terminal should be open or VDD voltage (LSB first) or GND voltage
(MSB first)
