TDA8547TS
General description
The TDA8547TS is a two channel audio power amplifier for an output power of 2 x 0.7 W with a 16 W 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 W load can be obtained. The circuit contains two BTL amplifiers with a complementary 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. When only one channel is used the maximum output power is 1.2 W.
Features
- Selection between output channels
- 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, VCC and across the load
- Thermally protected.
