ASAHI KASEI
(AVSS=DVSS=0V; Note 1)
Note 1. All voltages with respect to ground.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
(AVSS=DVSS=0V; Note 2)
Note 2. All voltages with respect to ground.
(Ta= 40 85 C; VDD=3.0 3.6V; TVDD=3.0~5.5V; data=20bit; measurement bandwidth=20Hz~FSO/2;
Note 3. Measured by Rohde & Schwarz UPD04, Rejection Filter= wide, 8192point FFT.
Note 4. The “0.33” is the ratio of FSO/FSI when FSI is 96kHz and FSO is 32kHz
Note 5. The “6” is the ratio when FSI is 8kHz and FSO is 48kHz.
