Note 3: POK threshold when VOUT is rising is nominally 92%. This threshold is 90% when VOUT is falling. After crossing
the 90% level, there is a 256 clock cycle (~213µs at 1.2 MHz) delay before POK is de-asserted. The 90% and 92% levels
are nominal values. Expect these thresholds to vary by ±3%.
Note 4: Parameter not production tested but is guaranteed by design.
Note 5: Rise time calculation begins when AVIN > V
Note 6: V
Note 7: M/S pin is ternary. Ternary pins have three logic levels: high, float, and low. This pin is meant to be strapped to
VIN through an external resistor, strapped to GND, or left floating. The state cannot be changed while the device is on.
