Typical Operating Characteristics

= 3.3V, T

= +25°C, unless otherwise noted.)

Note 1: All voltages referenced to ground.

Note 2: Tracking accuracy is defined as V

OUT

- V

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

Note 5: EEPROM programming time is the hold time required after the DS4303 has completed self-adjustment before V

or V

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.
