Data sheet:
Material Declaration:
The HFDA90D is a new STMicroelectronics class-D audio amplifier, specifically designed for automotive applications in the latest BCD technology.
The HFDA90D integrates advanced solutions for an excellent GSM noise immunity combined with the advantages of 2 MHz switching PWM class-D output stages. This configuration allows outstanding audio performance while designing a compact and inexpensive application.
The HFDA90D supports wide band applications up to 40 kHz, with extremely low level of noise and low THD.
Moreover, it features a broad diagnostics matrix, to support the most demanding OEM requirements in terms of speaker control and system robustness/reliability. The HFDA90D supports start/stop cranking down to 4.5 V and is housed in a very compact and thin LQFP48L 7x7x1.4 mm package, making it suitable for any level of automotive application.
