STPA003 - 4 x 52 W quad bridge power amplifier

General Description

The STPA003 is a MOSFET class AB audio power amplifier, designed for high-power car radio.

In addition to the outstanding output current capability and distortion performance, the STPA003 is extremely robust against several kinds of fortuitous misconnection.

Key Features

  • High output power capability:.
  • 4 x 52 W/4 Ω max.
  • 4 x 30 W/4 Ω @ 14.4 V, 1 kHz, 10 %.
  • 4 x 85 W/2 Ω max.
  • 4 x 55 W/2 Ω @ 14.4V, 1 kHz, 10 %.
  • MOSFET output power stage.
  • Capable to operate in low voltage conditions (e. g. : “Start - Stop”).
  • Excellent GSM noise immunity.
  • Excellent 2 Ω driving capability.
  • Hi-Fi class distortion.
  • Low output noise.
  • Standby function and mute function.
  • Automute at min. supply voltage detectio.
