TPA3131D2RHBR TI Audio Amplifiers
The TPA3131D2RHBR is a 2 × 4-W stereo, analog input Class-D audio amplifier from Texas Instruments operating over a wide supply voltage range of 4.5V to 26V, making it automotive load-dump compliant. The device supports multiple output configurations including stereo 2 × 4 W into 8-Ω BTL load at 7.4V and mono configurations, with power efficiency greater than 90% combined with low idle loss for heat sink-free operation. It features advanced oscillator/PLL circuits with multiple switching frequency options for AM avoidance, master and slave synchronization capability up to 1.2-MHz switching frequency, feedback power stage architecture with high PSRR, programmable power limit, and differential/single-ended inputs. Housed in a 32-pin VQFN (RHB) package, it operates over -40°C to 85°C. Applications include automotive audio systems, portable speakers, and consumer electronics.
