2 Noise performance is based on the bench data for TA = −40°C to +85°C.

Software master power-down indicates that the clocks are turned off. Automatic power-down indicates that there is no dither or zero

input signal with clocks on; the device enters soft power-down after 2048 cycles of zero input values. Quiescent indicates triangular dither

with zero input signal. All specifications are typical, with a 48 kHz sample rate, in stereo mode, unless otherwise noted.
