PIN/FUNCTION
No. Pin Name I/O Function
1 VREFL O Lch Reference Voltage Pin, 3.75V
Normally connected to GNDL with a 10uF electrolytic capacitor and
a 0.1uF ceramic capacitor
2 GNDL - Lch Reference Ground Pin, 0V
3 VCOML O Lch Common Voltage Pin, 2.5V
4 AINL+ I Lch Analog positive input Pin
5 AINL- I Lch Analog negative input Pin
6 ZCAL I Zero Calibration Control Pin
This pin controls the calibration reference signal.
"L":VCOML and VCOMR
"H":Analog Input Pins(AINL

7 VD - Digital Power Supply Pin, 3.3V
8 DGND - Digital Ground Pin, 0V
9 CAL 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.

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.
