GENERAL DESCRIPTION
The TDA1561Q is a monolithic power amplifier in a 13 lead single-in-line (SIL) plastic power package. It contains two identical 23 W amplifiers. The dissipation is minimized by switching from SE to BTL mode, only when a higher output voltage swing is needed. The device is primarily developed for car radio applications.

FEATURES
• Low dissipation due to switching from Single-Ended (SE) to Bridge-Tied Load (BTL) mode
• High Common Mode Rejection Ratio (CMRR)
• Mute/standby/operating/SE-only (mode select pin)
• Zero crossing mute and standby circuit
• Load dump protection circuit
• Short-circuit safe to ground, to supply voltage and across load
• Loudspeaker protection circuit
• Device switches to single-ended operation at excessive junction temperatures.
