NXP放大器 音頻IC TDA8542TS

General description
  


The TDA8542TS is a two channel audio power amplifier for an output power of 2 x 0.7 W with a 16 ? load at a 5 V supply. At a low supply voltage of 3.3 V an output power of 0.6 W with an 8 ? load can be obtained. The circuit contains two Bridge-Tied Load (BTL) amplifiers with a complementary PNP-NPN output stage and standby/mute logic. The TDA8542TS is available in a SSOP20 package.

 



Features and benefits
 

• Flexibility in use
• Few external components
• Low saturation voltage of output stage
• Gain can be fixed with external resistors
• Standby mode controlled by CMOS compatible levels
• Low standby current
• No switch-on/switch-off plops
• High supply voltage ripple rejection
• Protected against electrostatic discharge
• Outputs short-circuit safe to ground, V_CCand across the load
• Thermally protected.

Applications

• Portable consumer products
• Personal computers
• Motor-driver (servo).
