30W bridge car radio amplifier TDA7256

Description of TDA7256:

The TDA7256 is a class AB fully protected bridge power amplifier designed for car radio application. The high current capability allows to dirve low impedance loads up to 22 Ohm. The differential inputs availability makes it particularly suitable for boosters and active loudspeakers applications

Features of TDA7256:
  • NO AUDIBLE POP DURING MUTE AND
  • STANDBY OPERATIONS
  • MUTING TTL COMPATIBLE
  • VERY LOW STANDBY CONSUMPTION
  • PROGRAMMABLE TURN ON DELAY
  • DIFFERENTIAL INPUT
  • SHORT CIRCUIT PROTECTIONS:
  • RL SHORT - OUT TO GROUND - OUT TO VS
  • OTHER PROTECTIONS:
  • Load dump voltage surge
  • LoudspeakerDC current
  • Very inductive load
  • Overrating temperature
  • Open ground
