RF-to-Bits tuner chips simplify vehicle head unit designs
Using the remote tuner solution from Maxim Integrated Products, Inc., designers can significantly simplify the head unit design of a vehicle and reduce cables. The MAX2175 RF to Bits tuner within the solution eliminates the need to rework the vehicle’s hardware to support worldwide radio standards, allowing updates by simply changing the vehicle’s software. Traditional radio architecture […]

Automotive-specific Class-D audio amplifier eliminates up to 18 external components
Texas Instruments today introduced the first 2.1-MHz Class-D audio amplifier specifically designed for automotive applications. Supporting high-resolution 96-kHz digital input, the compact TAS6424-Q1 enables high-fidelity audio with low distortion in automotive infotainment applications. The TAS6424-Q1 enables the use of smaller external filters and eliminates up to 18 external components to reduce system size and cost […]
