2 / 24 page 1997 Aug 14 2 Philips Semiconductors Preliminary specification 2 × 23 W high efficiency car radio power amplifier TDA1561Q 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. 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.
