产品概述

描述

HFDA801A is the new ST class-D audio amplifier, specifically designed for automotive applications in the latest BCD technology. The HFDA801A integrates a 24-bits 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. HFDA801A 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. HFDA801A 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 HFDA801A is suitable for any level of automotive application.
