(1) End point fit between codes 256 to 65280
(2) When using an external reference VREF = VREFIN. Otherwise, VREF = 2.5V (internal reference voltage)
(3) Temporary overload condition protection. Junction temperature can be exceeded during current limit. Operation at temperatures greater than the specified maximum junction temperature can impair device reliability.
(4) Specified by design and characterization, not production tested.
(5) Time to exit power-down mode to normal operation. Measured from last rising edge of CS to 90% of DAC final value.
