STMicroelectronics TDA Power Amplifiers

STMicroelectronics TDA Power Amplifiers are dual-bridge and quad-bridge car radio amplifiers. They are designed with BCD technology, in order to  include a wide range of innovative features in a compact and flexible device. STMicroelectronics TDS Power Amplifiers are equipped with complete diagnostics array that communicates the status of each speaker through the I2C bus.

Features

  • Multipower BCD technology
  • MOSFET output power stage
  • DMOS power output
  • High efficiency (class SB)
  • High output power capability 4Wx25W/4Ω out power @ 14.4V, 1kHz, 10% THD, 4x45W max power
  • 2Ω driving capability (64W max power)
  • Full I2C bus driving
    • Standby
    • Independent front/rear soft play/mute
  • I2C bus digital diagnostics (including DC and AC load detection)
  • High efficiency enable/disable
  • Flexible fault detection through integrated diagnostic
  • DC offset detection
  • Four independent short circuit protection
  • Clipping detector pin with selectable threshold (2%/10%)
  • Standby/mute pin
  • Linear thermal shutdown with multiple thermal warning
  • ESD protection
  • Very robust against misconnections
  • Improved SVR suppression during battery transients
  • Capable to operate down to 6V (e.g. "Start-stop")
