Multi-purpose high-gain power amplifier

Features

High gainOperating voltage from 8 to 28 VLow distortionFew external components, fixed gainHigh output powerCan be used as a stereo amplifier in bridge-tied load (BTL) or quad single-ended (SE) amplifiersSingle-ended mode without loudspeaker capacitorMute and standby mode with one- or two-pin operationDiagnostic information for Dynamic Distortion Detector (DDD), high temperature (145 °C) and short-circuitNo switch on/off plops when switching between ‘standby’ to ‘mute’ and from ‘mute’ to ‘on’Low offset variation at outputs between ‘mute’ and ‘on’Fast mute on supply voltage drops.Reverse polarity safe (with protection diode added)Short-circuit proof to ground, positive supply voltage on all pins and across loadESD protected on all pinsThermal protection against temperatures exceeding 150 °CLoad dump protectionProtected against open-circuit ground pins and output short-circuited to supply ground.

4 x 13 W single-ended power amplifiers

FEATURES
Requires very few external components High output power Fixed gain Diagnostic facility (distortion, short-circuit and temperature detection) Good ripple rejection Mode select switch (operating, mute and standby) AC and DC short-circuit safe to ground and to VP Low power dissipation in any short-circuit condition Thermally protected Reverse polarity safe Electrostatic discharge protection No switch-on/switch-off plop Flexible leads Low thermal resistance Identical inputs.
GENERAL DESCRIPTION
The TDA8511J is an integrated class-B output amplifier in a 17-lead DIL-bent-SIL power package. It contains 4 × 13 W single-ended amplifiers.
