FUNCTIONAL DESCRIPTION
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.
