Product specification
Low-power stereo bitstream ADC/DAC
UDA1309H
There are different modes in which the UDA1309H can operate. These modes can be selected as shown in Table 3 and
Fig.5. In mode a, the digital filters clock is switched off. Switching over to one of the ADC active modes (b, c or d) initiates
a reset sequence of the digital filters. This mode should be activated immediately after power-on for at least 2 clock
periods.
