POWER CONSUMPTION
(Ta=25ºC; AVDD=DVDD=3.3V; DVDD18=1.8V; VSS1=VSS2=0V, fin=1 KHz, 24 bit, fs=8 KHz (CKM mode = 0),
DSPS=BITFS=PMOSC bits= “0” PMMB bit=“1”, DSP running with programmed connecting DIN2 with DOUT1 and
DIN1 with DOUT3.)

Note 16. The Consumption of DVDD18 depends on the master clock frequency and the step size of the DSP program.
(BITFS bit = “2h” and DSPS bit = “0”)
Note 17. All digital input pins are fixed to each supply pin (DVDD or VSS1).
Note 18. The condition of maximum values specifies Ta=Tmin~Tmax, AVDD=DVDD=3.0~3.6V and
DVDD18=1.7~1.9V.
