TAS5110DADR Audio Power Amplifier IC 2-Channel (Stereo) Class D
The TAS5110DADR, manufactured by TI, is a high-performance 50W digital audio power amplifier designed for stereo (2-channel) applications. Built on TI's PurePath Digital™ technology, it integrates a PWM power stage with advanced features such as digital inputs, mute functionality, short-circuit protection, thermal shutdown, and low-power standby mode. The component operates with a 3 V to 3.6 V supply voltage, making it suitable for battery-powered systems, while its Class-D architecture ensures high efficiency (>90%) and minimal heat generation.
The TAS5110DADR delivers 50 W per channel into 6 Ω loads (stereo) with a 16.5 V to 26.5 V bias supply (for PWM operation), enabling robust audio performance. Its digital input interface simplifies connectivity to microcontrollers or DSPs, while built-in protections (overcurrent, overtemperature, and undervoltage lockout) enhance reliability. The chip features a low quiesient current of 16 mA (typical) and shutdown current of 1 μA, optimizing power efficiency in standby modes. Electrically, it has a propagation delay of 300 ns and switching frequency of 250 kHz to 1 MHz, allowing flexibility in design.
TAS5110DADR audio amplifier Application Scenarios
The TAS5110DADR excels in consumer audio applications requiring high power and compact form factors. In portable Bluetooth speakers, it drives dual 50 W channels while minimizing battery drain due to its Class-D efficiency. For soundbars and home theater systems, its stereo output and low distortion deliver immersive sound without requiring external heatsinks. In automotive infotainment, it powers cabin speakers with built-in protections against voltage spikes and thermal stress.
