TPA3116D2DADR Class-D Audio Amplifier IC 2-Channel (Stereo)
The TPA3116D2DADR is a high-efficiency, mono Class-D audio amplifier from Texas Instruments, designed to deliver up to 50W of output power (with 4Ω load at 21V supply) for premium sound quality in consumer electronics, portable speakers, and automotive audio systems. This advanced amplifier operates across a wide input voltage range of 4.5V to 26V, supporting both battery-powered and line-powered applications while maintaining >90% power efficiency to minimize heat generation. The device features advanced modulation schemes (BD modulation) that reduce electromagnetic interference (EMI) and eliminate the need for output filter inductors in most applications, simplifying PCB design and reducing BOM costs.
Engineered for superior audio performance, the TPA3116D2DADR incorporates low-noise preamplifier circuitry with <0.1% THD+N (Total Harmonic Distortion + Noise) across the 20Hz–20kHz audio band, ensuring high-fidelity sound reproduction. Its integrated feedback loop provides excellent power supply rejection (PSRR > 60dB), minimizing audible noise from unstable power sources. The amplifier includes multiple protection features such as overcurrent protection (OCP), undervoltage lockout (UVLO), and thermal shutdown, safeguarding both the IC and connected speakers. Packaged in a 32-pin HTSSOP (PowerPAD™), the device achieves optimal thermal dissipation while maintaining a compact footprint for space-constrained designs.
