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.
