TDA7437N
6/23
Note 1: WIN represents the MUTE programming bit pair D6, D5 for the zero crossing window threshold
Note 2: Internall pullup resistor to Vs/2; "LOW" = softmute active
Note: The ANGND and DIGGND layout wires must be kept separated. A 50
resistor is recommended to be put as far as possible from the
device.
The CLD - and CDR - can be shortcircuited in applications providing 3 wires CD signal
CLD - = DIFFINLGND
CDR - = DIFFINRGND
