PARAMETER
plastic DIL-bent-SIL power package; 13 leads (lead length 12 mm)
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.
