is measured while continuously writing code 2048 to the DAC. For V
IH
< DVDD - 0.7V and V
IL
> 0.7V
supply current will increase.
9.
Typical supply current
in powerdown mode is 10nA. Production test limits are wider for speed of test.
10.
Slew rate results
are for the lower value of the rising and falling edge slew rates.
11.
Settling time
is the time taken for the signal to settle to within 0.5LSB of the final measured value for both rising and
falling edges. Limits are ensured by design and characterisation, but are not production tested.

generated with
a sampling frequency f
