Product overview

Description

HFDA802 is the new ST class-D audio amplifier, specifically designed for automotive applications in the latest BCD technology. The HFDA802 integrates a 24-bit 120 dB DAC conversion, and features 2 MHz switching PWM class D output stage. This configuration enables the design of a compact and inexpensive application, reaching at the same time outstanding level of audio performances. HFDA802 supports wide band applications (80 kHz), with extremely low level of noise and low THD. Moreover it features the most complete diagnostic matrix, including full diagnostic in play to support the most demanding OEM requirements in terms of speaker control and system robustness/ reliability. HFDA802 supports start stop cranking down to 4.5 V (5 V at turn on) and it is housed in a very compact and thin LQFP 10x10 package. Thus the HFDA802 is suitable for any level of automotive application.
