Note) *1: The offset voltage is denoted by considering a typical value and the maximum value as σ and 3σ, respectively.
*2: The same specification is applied to the external clock mode and internal clock (spread clock mode).
All the values of analog characteristics were obtained in our evaluation circumstance.
Depending upon pattern layout etc., characteristics may vary.
The measurement is performed with an 8 or 4 resistor connected in series with a 30H coil as an output load.
