SLAS831C – MARCH 2014 – REVISED AUGUST 2014
Typical Characteristics (continued)
all specifications at TA = 25°C, AVDD = 3.3V, DVDD = 3.3V, IOVDD = 3.3V, Master Mode, Single Speed Mode, fS = 48kHz,
system clock = 256×fS, 24-bit data (unless otherwise noted)
Figure 17. Linearity, Input versus Output
7 Parameter Measurement Information
Figure 18. PCM186x Test Circuit
All typical characteristics for the devices are measured using the EVM and an Audio Precision SYS-2722 Audio
Analyzer. A PSIA interface is used to allow the I2S interface to be driven directly into the SYS-2722.
