Production Data

WM8772EFT – 32 LEAD TQFP

PD Rev 4.2 October 2005

LEFT JUSTIFIED MODE

In left justified mode, the MSB of DIN1/2/3 is sampled by the WM8772EFT on the first rising edge of

DACBCLK following a DACLRC transition. The MSB of the ADC data is output on DOUT and

changes on the same falling edge of ADCBCLK as ADCLRC and may be sampled on the rising edge

of ADCBCLK. ADCLRC and DACLRC are high during the left samples and low during the right

samples (Figure 47).
