PROGRAMMABLE SETTLING TIME

Settling time is a software selectable 12µs or 4µs typical, to within ±0.5LSB of final value. This is

controlled by the value of D14. A ONE defines a settling time of 4µs, a ZERO defines a settling time of

12µs.

PROGRAMMABLE POWER DOWN

The power down function is controlled by D13. 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.
