Notes for use

(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 IC 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, IC 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 IC.

(4) GND voltage

Please keep GND voltage lowest of any other terminal of this IC. Please confirm other terminal voltages is 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 IC direction and displacement when mounting IC on PCB. If you assemble them by

mistake and electrify it, IC might be destroyed. And it is happen to short among IC 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 inserted between the analog output and ground in order to eliminate noise.

A capacitance up to 100pF is recommended (including the capacitance of the wire).
