Parameter
All digital input pins (SDA, SCL, LDAC) are tied to “High”, Output pins are unloaded, code = 0 x 000.
The power-up ramp rate measures the rise of V
This parameter is ensured by design and not 100% tested.
This parameter is ensured by characterization and not 100% tested.
Test code range: 100 - 4000 codes, V
Time delay to settle to a new reference when switching from external to internal reference or vice versa.
This parameter is indirectly tested by Offset and Gain error testing.
Within 1/2 LSB of the final value when code changes from 1/4 of to 3/4 of full scale.
This time delay is measured from the falling edge of ACK pulse in I
This time delay is not included in the output settling time specification.
