1. The LSI output level = 0.3058AVDD Vrms.

2. Signal-to-noise is measured following a device reset, with DATA = 0 (DI = LOW). Under these conditions, the signal-to-noise ratio includes noise-shaper

noise.

3 V operation: DVSS = AVSS = XVSS = 0 V, DVDD = AVDD = XVDD = 3 V, AVDD = AVDDL = AVDDR,

CKSL = 0 V, deemphasis OFF, crystal oscillator frequency fOSC = 16.9344 MHz, Ta = 25 °C
