Timing Diagrams

FLAG Delay Time Interval Step Size, from D2:D0= 001b to 111b.

FLAG is Asserted LOW when Audio Input is Below Threshold. (See Table 1, page 7)

NOTES:

6. When pin is open, voltage is pulled up through current source to VCC.

7. Limits should be considered typical and are not production tested.

8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization

and are not production tested.
