Notes:

6. Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only;

functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be

affected by exposure to absolute maximum rating conditions for extended periods of time.

7. The absolute maximum VDD of 4V is a transient stress rating and is not meant as a functional operating condition. It is not recommended to

operate the device at the absolute maximum rated conditions for any period of time.

(During ‘Sleep’ Period)

VOUTPUT = VDD/2, ENABLE = GND, VDD = 1.8V

8.93

VOUTPUT = VDD/2, ENABLE = GND, VDD = 3V

IDD_AUTORUN

Average Supply Current in Auto-Run

Mode when ENABLE = Logic High

(or VDD) Continuously

(The sampling frequency when

ENABLE = High continuously is

6.25kHz)

VOUTPUT = VDD/2, ENABLE = VDD, VDD = 1.8V

(Note 10)

1.01

1.3

VOUTPUT = VDD/2, ENABLE = VDD, VDD = 3V

(Note 10)

1.8

Notes:

8. When power is initially turned on, the operating VDD (1.6V to 3.6V) must be applied to guarantee the output sampling.

After the supply voltage reaches minimum operating voltage, the output state is valid after 140us after the ENABLE pin pulled or clocked high.

9. Typical data is at TA = +25°C, VDD = 1.8V unless otherwise stated.

10. The parameters are not tested in production, they are guaranteed by design, characterization and process control.
