(1)

Analog performance specifications are measured using the System Two™ Cascade audio measurement system by Audio Precision™ in

the averaging mode.

(2)

Conditions in 192-kHz operation are system clock = 128 fS and oversampling rate = 64 fS of register 18.

7.5 Electrical Characteristics

all specifications at TA = 25°C, VCC = 5 V, fS = 44.1 kHz, system clock = 384 fS, and 24-bit data (unless otherwise noted)
