TDA7437
ELECTRICAL CHARACTERISTICS (continued)
Note 1: WIN represents the MUTE programming bit pair D
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
The CLD - and CDR - can be shortcircuited in applications providing 3 wires CD signal
CLD - = DIFFINLGND
CDR - = DIFFINRGND
