The STMicroelectronics HFA80A is a new STMicroelectronics class-D audio amplifier, specifically designed for automotive applications in BCD9s technology. The HFA80A integrates advanced solutions for an excellent radiated noise immunity combined with the advantages of 2 MHz switching PWM class-D output stages. This configuration allows outstanding audio performances while designing a compact and inexpensive application. The HFA80A supports wide band applications with extremely low level of noise and low THD. Moreover, it features a broad diagnostics matrix able to support the most demanding OEM requirements in terms of speaker control and system robustness/reliability. The HFA80A supports start/stop cranking down to 4.5 V and is housed in a very compact and thin LQFP 7x7 package, making it suitable for any level of automotive application.
