Typical Operating Characteristics
(V
CC
= 3.3V, T
A
= +25°C, unless otherwise noted.)
Note 1: All voltages referenced to ground.
Note 2: Tracking accuracy is defined as V
OUT
- V
IN
after the DS4303 has completed self-adjustment.
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
OUT
requires to self-adjust. The settling time is determined by the following
formula:
∆V
OUT
x t
ST
.
Note 5: EEPROM programming time is the hold time required after the DS4303 has completed self-adjustment before V
IN
or V
CC
can be removed or before ADJ can be toggled low once again.
Note 6: Turn-on time is defined as the time required for V
OUT
to reach its specified accuracy after the required supply voltage is
applied.
Note 7: V
OUT
not loaded.
Note 8: Guaranteed by design.
