(Note 1) To use the IC at temperatures over Ta25°C, derate power rating by 27.4mW/°C.
When mounted on a four-layer glass epoxy board measuring 74.2mm x 74.2mm x 1.6mm.
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.

Operation of each block
(1) Regulator (VDAC)
This is a regulator block for setting a reference voltage of DAC.
VDAC has enable function so that if EN=Low, shut down is performed, or EN=High, settable VDAC voltage by FB voltage
and external resistor. At this time, VDAC voltage < 5.5[V] (MAX operating voltage) should be configured.
VDAC output capacity (C11) is set over 1[µF].
Phase compensation (C12) is able to use as OPEN, but it is recommended to set the PCB pattern.

R12
Example) In case R11=18[kΩ], R12=2 [kΩ], VDAC equals to 5.0[V].
10[kΩ] to 100[kΩ] is a recommended range for the sum of setting value of R11,R12. If the setting is below 10[kΩ],
consumption current may increase, thus resulting in degraded power efficiency. If the setting exceeds 100[kΩ], offset
voltage is likely increase due to the input bias current.
