Description

The TDA8551; TDA8551T is a one channel 1 W Bridge-Tied Load (BTL) audio power amplifier capable of delivering 1 W output power to an 8 W load at THD = 10% using a 5 V power supply. The circuit contains a BTL power amplifier, a digital volume control and standby/mute logic. The TDA8551T comes in an 8 pin SO package and the TDA8551 in a 8 pin DIP package.

Features

• One pin digital volume control
• Volume setting with UP/DOWN pulses
• Flexibility in use
• Few external components
• Low saturation voltage of output stage
• 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_P and across the load
• Thermally protected.

Applications

• Portable consumer products
• Personal computers
• Telephony.
