Datasheet DS4303 (Analog Devices) - 3

Electronically Programmable Voltage Reference DS4303 NONVOLATILE MEMORY CHARACTERISTICS
(VCC = +2.4V to 3.6V, unless otherwise noted.)
PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS
Programming Cycles +70°C (Note 8) 50,000 Cycles
Note 1:
All voltages referenced to ground.
Note 2:
Tracking accuracy is defined as VOUT - VIN 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 VOUT requires to self-adjust. The settling time is determined by the following formula: ∆VOUT x tST.
Note 5:
EEPROM programming time is the hold time required after the DS4303 has completed self-adjustment before VIN or VCC can be removed or before ADJ can be toggled low once again.
Note 6:
Turn-on time is defined as the time required for VOUT to reach its specified accuracy after the required supply voltage is applied.
Note 7:
VOUT not loaded.
Note 8:
Guaranteed by design.
