4 × 40 W BTL quad car radio power amplifier
FEATURES:
Requires very few external components
High output power
Low output offset voltage
Fixed gain
Diagnostic facility (distortion, short-circuit and temperature pre-warning)
Good ripple rejection
Mode select switch (operating, mute and standby)
Load dump protection
Short-circuit safe to ground and to VP and across the load
Low power dissipation in any short-circuit condition
Thermally protected
Reverse polarity safe
Electrostatic discharge protection
No switch-on/switch-off plop

Low thermal resistance
Pin compatible with the TDA8568Q, except for the gain.
GENERAL DESCRIPTION:
The TDA8571J is a integrated class-B output amplifier contained in a 23-lead Single-In-Line (SIL) plastic power package. It contains four amplifiers in a BTL configuration, each with a gain of 34 dB. The output power is 4 × 40 W (EIAJ) into a 4 Ω load.
APPLICATIONS:
Primarily developed for car radio applications
