FDA803U Datasheet 1 X 45w Class-d Digital Input Automotive Power Amplifier

Manufacturer: STMicroelectronics

Overview: FDA803U 1 x 45 W class D digital input automotive power amplifier with diagnostics, wide voltage operation range for car audio and telematic Datasheet - production data 3RZHU662 6OXJXS .

General Description

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).

Key Features
