Note 1: All voltages referenced to ground.
Note 2: Tracking accuracy is defined as V
Note 3: Quantization refers to the size of the voltage steps used to track the input signal.
Note 4: Settling time is the maximum amount of time V
Note 5: EEPROM programming time is the hold time required after the DS4305 has completed self-adjustment before V
Note 6: Turn-on time is defined as the time required for V
Note 7: V
Note 8: Guaranteed by design.
