High efficiency 2 × 25 W/4 Ω
stereo car radio power amplifier
Preliminary specification
TDA1564
FEATURES
• Low dissipation due to switching from Single-Ended
(SE) to Bridge-Tied Load (BTL) mode
• Differential inputs with high Common Mode Rejection
Ratio (CMRR)
• Mute/standby/operating (mode select pin)
• Load dump protection circuit
• Short-circuit safe to ground, to supply voltage and
across load
• Loudspeaker protection circuit
• Offset detection for each channel
• Device switches to single-ended operation at excessive
junction temperatures
• Thermal protection at high junction temperature (170°C)
• Clip detection at THD = 2.5 %
• Diagnostic information
(clip/protection/prewarning/offset).
GENERAL DESCRIPTION
The TDA1564 is a monolithic power amplifier in a 17-lead
single-in-line (SIL) plastic power package. It contains two
identical 25 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.
