• Minimum external components count:

-no bootstrap capacitors -no Boucherot cells -internally fixed gain 20 dB

• Standby function (CMOS compatible)
• No audible pop during standby operations
• Diagnostic facilities:

-clip detector -output to GND short-circuit detector -output to VS short-circuit detector -soft short-circuit check at turn-on -thermal shutdown warning

• Protection

-Output AC/DC short circuit -Soft short-circuit check at turn-on -Thermal cutoff/limiter to prevent chip from overheating -High inductive loads -ESD
