4. Analog Output
The analog output is single-ended and the output signal range is typically 0.86 x AVDD Vpp centered on
VCOM. The digital input data format is two’s compliment. Positive full-scale output corresponds to
7FFFFFFFH (@32bit) input code, Negative full scale is 80000000H (@32bit) and VCOM voltage ideally is
00000000H (@32bit). The Out-of-Band noise (shaping noise) generated by the internal delta-sigma
modulator is attenuated by an integrated switched capacitor filter (SCF) and a continuous time filter
(CTF).
5. Connection to Digital Circuit
To minimize the noise from digital circuits, the digital output of the AK4601 must be connected to CMOS
or low voltage logic ICs such as 74HC and 74AC for CMOS and 74LV, 74LV-A, 74ALVC and 74AVC for
low voltage logic ICs.
