Sales Briefcase
  • The FDA803U is a single bridge class D amplifier, designed in the most advanced BCD technology, intended for any automotive audio application (car radio, telematics and e-call, noise and tone generators, etc).

    The FDA803U integrates a high performance D/A converter together with powerful MOSFET outputs in class D, so it is very compact and powerful, moreover it reaches outstanding efficiency performances (90%).
    It has a very wide operating range: it can be operated both with standard car battery levels (5.5-18 V operating, compatible to load dump pulse) and with external step-down generated voltages or emergency battery (since it is compatible to minimum 3.3 V operative).
    The feedback loop includes the output L-C low-pass filter, allowing superior frequency response linearity and lower distortion.
    FDA803U is configurable through I2C bus interface and integrates a complete diagnostics array specially intended for automotive applications including innovative open load and DC offset detection in play mode.
    Thanks to the solutions implemented to solve the EMI problems, the device is intended to be used in the standard single DIN car-radio box together with the tuner.
    Moreover FDA803U features a configurable power limiting function, and can be optionally operated under no I2C mode ('legacy mode').
