TAS6424EQDKQRQ1 Amplifier IC 4-Channel (Quad) Class D 56-HSSOP
The TAS6424EQDKQRQ1 is a high-performance automotive-grade Class-D digital audio power amplifier designed by Texas Instruments (TI), compliant with AEC-Q100 standards for automotive reliability. It integrates four independent 75W channels (4Ω load) with a 2MHz switching frequency, supporting a wide power supply range of 4.5V to 26.4V. The device is housed in a compact 56-pin HSSOP package, optimized for space-constrained automotive audio systems. Its core features include low THD+N (0.02%), high power efficiency, and robust protection mechanisms such as over-temperature, over-current, and over-voltage safeguards. Additionally, it supports multiple digital audio interfaces (I2S, TDM, PCM) and includes built-in volume control, diagnostics, and low-power modes for energy savings.
TAS6424EQDKQRQ1 Applications
The TAS6424EQDKQRQ1 is ideal for automotive infotainment systems, including head units, active noise cancellation (ANC) modules, and multi-speaker setups. Its high power density and low noise make it suitable for premium audio brands requiring immersive sound quality. The chip’s automotive-grade certification ensures compliance with stringent industry standards for reliability, electromagnetic compatibility (EMC), and temperature resilience, making it a preferred choice for electric vehicles (EVs) and traditional combustion engine vehicles alike.
Alternative Class-D audio amplifier Models
● TAS6422QDKQRQ1: A 2-channel variant of the TAS6424, sharing the same die but with half the channels, suitable for cost-sensitive automotive audio designs.
● TAS6424LSQDKQRQ1: A functionally equivalent alternative to the TAS6424EQDKQRQ1, with identical pinouts and performance, often used as a drop-in replacement during supply shortages.
● TAS5825MRHBR: A 2-channel Class-D amplifier from TI with similar power output (100W) but optimized for home audio, lacking automotive-specific certifications.
● TAS5760MDCAR: A legacy 4-channel amplifier with lower power (50W per channel) and no AEC-Q100 compliance, suited for non-automotive applications.
