Startup Time
Time [sec]
Startup time can be calculated as follows.
1.
Startup time (TYP) = 650[ms] (Table 5.2)
2. CCOM=10uF×(1±α/100)
CCOM is a capacitor connected to Terminal C_L/C_R including capacitance variance.
α=Capacitance variance[%]
3. Startup time = Start up time(TYP)×(1±α) [ms]
For example, CCOM=11µF then α=(11µF-10µF)/10µF=10[%]
So, Startup time = 650ms×（1+10/100） = 715[ms]
Notes:
− Two usages of RL load connection.
− Case1: RL is connected to AVCC3_DAC /2 (Figure 8-9)
− Case2: The coupling capacitance must be inserted as shown in (Figure 8-10).
