TPA6304QDDVRQ1 is an AEC‑Q100 qualified four‑channel automotive Class‑D audio amplifier with analog input, delivering up to 27W per channel into 4‑ohm loads or 45W per channel into 2‑ohm loads under 14.4V supply, integrating 40V load‑dump protection, comprehensive load diagnostics via I2C interface and 2.1MHz high switching frequency to avoid AM‑band interference for vehicle audio systems.
Key highlights: AEC‑Q100 Grade‑1 automotive qualification supporting‑40°C to 125°C ambient temperature; high‑efficiency Class‑D architecture over 80% efficiency to reduce thermal dissipation; built‑in 40V load‑dump, short‑circuit, over‑temperature and DC offset protection; I2C‑controlled load diagnostics detecting open load, short circuit and tweeter faults; 2.1MHz switching frequency with spread‑spectrum function to meet CISPR25‑L5 EMC requirements; multiple programmable gain settings and PBTL parallel bridge‑tied‑load mode for higher output power.
This device is widely deployed for automotive infotainment head‑units, in‑car external audio amplifier modules, multi‑channel vehicle speaker drive systems, tweeter driving circuits and replacement solutions for traditional Class‑AB automotive amplifiers, serving passenger car audio and compact automotive sound equipment with strict EMI and reliability demands.
