Description

The FDA803D 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 FDA803D integrates a high performance D/A converter together with powerful

MOSFET outputs in class D, so it is very compact and powerful, moreover 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 is including the output L-C low-pass filter, allowing superior frequency

response linearity and lower distortion.

FDA803D is configurable through I2C bus interface and is integrating 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 FDA803D features a configurable power limiting function, and can be optionally

operated under no I2C mode ('legacy mode').
