The HAT2210RWS-E is a low-cost automotive-grade Audio Interface IC from Renesas. It is designed specifically for output and input audio signals in automotive infotainment systems. The device includes outputs and inputs for microphone, amplifier, analog audio line, and digital signals. It supports up to two balanced audio inputs, three unbalanced audio inputs, and two audio outputs. It also includes a dedicated input for a speed sensor signal, allowing the system to accurately detect the speed of the vehicle and adjust the sound system accordingly. The HAT2210RWS-E provides high signal-to-noise ratio thus ensuring clear and noise-free audio signal throughout the system. Additionally, it features an on-chip current-limiting feature for the amplifiers, enabling it to protect the amplifiers from over current induced short circuits.
