4. Analog Outputs
The analog outputs are also single-ended and centered around the VCOM voltage. The input signal range scales with the
supply voltage and nominally 0.6 x VREFH Vpp. The DAC input data format is 2’s complement. The output voltage is a
positive full scale for 7FFFFFH(@24bit) and a negative full scale for 800000H(@24bit). The ideal output is VCOM
voltage for 000000H(@24bit). The internal analog filters remove most of the noise generated by the delta-sigma
modulator of DAC beyond the audio passband.
DC offsets on analog outputs are eliminated by AC coupling since DAC outputs have DC offsets of a few mV.
Peripheral I/F Example
The AK4626A can accept the signal of device with a nominal 3.3V supply because of TTL input. The power supply for
output buffer (TVDD) of the AK4626A should be 3.3V when the peripheral devices operate at a nominal 3.3V supply.
Figure 26 shows an example with the mixed system of 3.3V and 5V.
