MAX5556
Low-Cost Stereo Audio DAC

Maxim Integrated
Power-Up
Once the MAX5556 recognizes a valid MCLK/LRCLK
ratio (256, 384, or 512), the analog outputs (OUTR and
OUTL) are enabled in stages using a glitchless ramping
routine. First, the outputs ramp up to the quiescent out-
put voltage at a rate of 5V/s typ (see Figure 11). After the
outputs reach the quiescent voltage, the converted data
stream begins soft-start ramping, achieving the full-scale
operation over a 20ms period.
If invalid clock signals are detected while the outputs
are DC ramping to their quiescent state, the outputs
stop ramping and hold their preset values until valid
clock signals are restored (Figure 12).
