The TPA2005D1-Q1 device is a 1.4-W high-efficiency filter-free class-D audio power amplifier in a SON or MSOP-PowerPAD package that requires only three external components.
Features like 84% efficiency, –71-dB PSRR at 217 Hz, improved RF-rectification immunity, and 15-mm2 total PCB area make TPA2005D1-Q1 ideal for low-power audio applications in infotainment and cluster.
The device allows for independent gain control by summing the signals from each function while minimizing noise to only 48 µVRMS. Additionally, the TPA2005D1-Q1 device offers fast start-up time of 9 ms with minimal pop and has short circuit and thermal protection.
