O

Calibration Active Signal Pin

"H" means the offset calibration cycle is in progress. Offset calibration starts

when RST goes "H". CAL goes "L" after 8704 LRCK cycles for DFS="L",

17408 LRCK cycles for DFS ="H".

10

RST

I

Reset Pin

When "L", Digital section is powered-down. Upon returning "H", an

offset calibration cycle is started. An offset calibration cycle should always

be initiated after power-up.
