AN7190K - Dual 20 W BTL power amplifier

AN7190K - Dual 20 W BTL power amplifier

FEATURES
• BTL 20 W × 2-channel (4R), Gv = 40 dB
• Built-in various protection circuits (thermal protection,short circuit to Vcc and short circuit to GND, Vcc-openshort circuit to Vcc, GND-open short circuit to GND, overvoltage and supply surge, and ASO, etc.)
Especially, the supply surge breakdown voltage is 100V or more.
GND open breakdown voltage is 16 V or more.
• Built-in standby function
Free from shock noise at STB on/off.
• Built-in muting function
Free from shock noise at mute-on/off.
Adapting attenuator method so that abnormal sound due to waveform deformation is not generated .
Attack time, recovery time are 50 ms or less.
• Reduction in external components
It eliminates the need for NF and BS electrolytic capacitors.
Muting function is not required, and power supply chokecoil is unnecessary.
• Provided with beep sound input pin
• 2R load guaranteed

APPLICATIONS
• Car audio
