Philips Semiconductors Preliminary specification 2 × 23 W high efficiency car radio power TDA1561Q amplifier FEATURES GENERAL DESCRIPTION • Low dissipation due to switching from Single-Ended The TDA1561Q is a monolithic power amplifier in a 13 lead (SE) to Bridge-Tied Load (BTL) mode single-in-line (SIL) plastic power package. It contains two identical 23 W amplifiers. The dissipation is minimized by • High Common Mode Rejection Ratio (CMRR) switching from SE to BTL mode, only when a higher output
