PROGRAMMABLE SETTLING TIME
Settling time is a software selectable 3.5
μ
s or 1
μ
s, typical to within
±
0.5LSB of final value. This is
controlled by the value of SPD
–
Bit D12. A ONE defines a settling time of 1
μ
s, a ZERO defines a
settling time of 3.5
μ
s.

PROGRAMMABLE POWER DOWN
The power down function can be controlled by PWR. A ZERO configures the device as active, or fully
powered up, a ONE configures the device into power down mode. When the power down function is
released the device reverts to the DAC code set prior to power down.
