Showing posts with the label TDA8581

Multi-purpose high-gain power amplifier


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.
