26 W BTL and 2 × 13 W SE or
4 × 13 W SE power amplifier
Preliminary specification
TDA8512J
1 FEATURES
• Requires very few external components
• High output power
• Low output offset voltage Bridge-Tied Load (BTL)
channel
• Fixed gain
• Good ripple rejection
• Mode select switch: operating, mute and standby
• Short-circuit safe to ground and across load
• Low power dissipation in any short-circuit condition
• Thermally protected
• Reverse polarity safe
• Electrostatic discharge protection
• No switch-on and switch-off plops
• Flexible leads
• Low thermal resistance
• Identical inputs: inverting and non-inverting.
2 APPLICATIONS
• Multimedia systems
• Active speaker systems (stereo with sub woofer or
QUAD).
3 GENERAL DESCRIPTION
The TDA8512J is an integrated class-B output amplifier in
a 17-lead Single-In-Line (SIL) power package. It contains
4 × 13 W Single Ended (SE) amplifiers of which two can be
used to configure a 26 W BTL amplifier.
