General Description: The TDA1515BQ is a monolithic integrated class-B output amplifier in a 13-lead single in-line (SIL) plastic power  package. The device is primarily developed for car radio applications, and also to drive low-impedance loads (down to  1,6 Ω). At a supply voltage VP = 14,4 V, an output power of 24 W can be delivered into a 4 Ω BTL (Bridge Tied Load),  or, when used as stereo amplifier, it delivers 2 × 12 W into 2 Ω or 2 × 7 W into 4 Ω.  Features: flexibility in use − mono BTL as well as stereo high output power low offset voltage at the output (important for BTL) large usable gain variation very good ripple rejection internal limited bandwidth for high frequencies low stand-by current possibility (typ. 1 µA), to simplify required switches; TTL drive possible low number and small sized external components high reliability. he following currently required protections are incorporated in the circuit. These protections also have pos...

GENERAL DESCRIPTION: The TDA1518BQ is an integrated class-B output amplifier in a 13-lead single-in-line (SIL) plastic power package. The device is primarily developed for car radio applications.  FEATURES: Requires very few external components Flexibility in use  stereo as well as mono BTL High output power (without bootstrap) Low offset voltage at output (important for BTL) Fixed gain Good ripple rejection Mute/stand-by switch Load dump protection A.C. and d.c. short-circuit-safe to ground and VP Thermally protected Reverse polarity safe Capability to handle high energy on outputs (VP = 0 V) No switch-on/switch-off plop Flexible leads Low thermal resistance Identical inputs (inverting and non-inverting) Compatible with TDA1516BQ (except gain).
