Philips SemiconductorsProduct specification
8 W BTL or 2 × 4 W SE power amplifierTDA1517ATW
FEATURES
• Requires very few external components
• Flexibility in use: mono Bridge-Tied Load (BTL) and
stereo Single-Ended (SE); it should be noted that in
stereo applications the outputs of both amplifiers are in
opposite phase
• High output power
• Low offset voltage at output (important for BTL)
• Electrostatic discharge protection
• Thermal protection
• Reverse polarity safe
• Capable of handling high energy on outputs (VP=0V)
• No switch-on/switch-off plop
• Low thermal resistance.
GENERAL DESCRIPTION
• Fixed gain
• Good ripple rejection
• Mode select switch (operating, mute and standby)
• AC and DC short-circuit safe to ground and V

The TDA1517ATW is an integrated class-AB output
amplifier contained in a plastic heatsink thin shrink small
outline package (HTSSOP20). The device is primarily
developed for multimedia applications.
The TDA1517ATW contains two identical amplifiers with differential input stages. This device can be used for
Bridge-Tied Load(BTL) or Single-Ended (SE) applications. The gain of each amplifier is fixed at 20 dB. A special feature
of this device is the mode select switch. Since this pin has a very low input current (<40 µA), a low cost supply switch
can be used. With this switch the TDA1517ATW can be switched into three modes:
• Standby: low supply current
• Mute: input signal suppressed
• Operating: normal on condition.
