Description
General part information
TAS2552 Series
The TAS2552 is a high efficiency Class-D audio power amplifier with advanced battery current management and an integrated Class-G boost converter. The device constantly measures the current and voltage across the load and provides a digital stream of this information.
The Class-G boost converter generates the Class-D amplifier supply rail. During low Class-D output power, the boost improves efficiency by deactivating and connecting VBAT directly to the Class-D amplifier supply. When high power audio is required, the boost quickly activates to provide significantly louder audio than a stand-alone amplifier connected directly to the battery.
The AGC automatically adjusts Class-D gain to reduce battery current at end-of-charge voltages, preventing output clipping, distortion and early system shutdown. The fixed gain is adjustable via I2C. The gain range is –7 dB to +24 dB in 1 dB steps.
