TAS5825MRHBR
Texas Instruments
The TAS5825M is a high-performance, stereo closed-loop Class-D with integrated auido processor with up to 192-kHz architecture.
The powerful DSP audio processing core support several advanced audio process flows. Even with 192-kHz architecture, TAS5825M provide a rich processing, such as 2×12 BQs, volume control, audio mixer, 2 Band DRC and a Full Band AGL. With 48-kHz or 96-kHz architecture, an integrated SRC (Sample rate convertor) detects the input sample rate change and auto convert to the target sample rate which DSP is running to avoid any audio artifacts, these process flows support richer processing, such as 2×15 BQs, 3-Band DRC, Full-band AGL (Automatic Gain Limiter), Smart Amplifier Algorithm (Speaker Thermal/Excursion Protection), Bass enhancement, Spatializer, THD manager and so on.

The TPS22971 is a space-saving single-channel load switch with controlled and adjustable Turn-ON slew rate and an integrated Power Good indicator. The device contains an N-channel MOSFET that can operate over a low input voltage range of 0.65 V to 3.6 V and can support a maximum continuous current of 3 A. A low on-resistance of 6.7-mΩ minimizes the power loss and voltage drop across the load switch. The switch is controlled by an on and off input (ON), which is capable of interfacing directly with low-voltage control signals.
By default, the TPS22971 has a Fast Turn-ON time to minimize system startup and wait time. The Adjustable Slew Rate can also be reduced to limit inrush current. A Power Good (PG) signal internally monitors the gate threshold and indicates when the switch is fully on. When the switch is disabled, a 150-Ω on-chip resistor quickly discharges the output to ground and keeps it from floating.
The TPS22971 is available in an ultra-small, space saving 8-pin WCSP package and is characterized for operation over the free-air temperature range of –40°C to 105°C and integrates thermal shutdown to turn off in case of overheating.
