26 W BTL and 2 × 13 W SE or 4 × 13 W SE power amplifier

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.

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
