• Manufacturer Part Number: ak4120
• Description: Sample Rate Converter With Mixer And Volume
• Manufacturer: AKM Semiconductor, Inc.

(VSS=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.
(VSS=0V; Note 2)
Note 2: All voltages with respect to ground.
(Ta=-40 85 C; VDD = 2.7 3.6V; data = 20bit; measurement bandwidth = 20Hz~ FSO/2; unless otherwise specified.)
Note 3. 32kHz~96kHz for INPUT#2 at Path Mode 0. 8kHz~96kHz at Path Mode 2 and 3.
Note 4. Min = 8kHz at Path Mode 2 and 3.
Note 5. Measured by Rohde & Schwarz UPD04, Rejection Filter= wide, 8192point FFT. Refer Figure 1 and Figure 2.
Note 6. The “0.667” is the ratio of FSO/FSI when FSI is 48kHz and FSO is 32kHz
Note 7. The “6” is the ratio when FSI is 8kHz and FSO is 48kHz.
