TDA8547 Datasheet | NXP Semiconductors

FEATURES - Selection between output channels - Flexibility in use - Few external ponents - Low saturation voltage of output stage - Gain can be fixed with external resistors - Standby mode controlled by CMOS patible 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, VCC and across the load - Thermally protected. GENERAL DESCRIPTION APPLICATIONS - Telemunication equipment - Portable consumer products - Personal puters - Motor-driver (servo). The TDA8547(T) is a two channel audio power amplifier for an output power of 2 × 1 W with an 8 Ω load at a 5 V supply. The circuit contains two BTL amplifiers with a plementary PNP-NPN output stage and standby/mute logic. The operating condition of all channels of the device (standby, mute or on) is externally controlled by the MODE pin. With the SELECT pin one of the output channels can be switched in the standby condition. This feature can be used for loudspeaker selection and also reduces the quiescent current consumption. The TDA8547T es in a SO16 package and the TDA8547 in a DIP16 package.
