Product Overview
The TAS2110 is a Texas Instruments digital input Class-D audio amplifier for Signal_Chain designs requiring a compact power-output stage. It is specified in a 32-pin QFN package with a 4.5 mm x 4 mm nominal body size, supporting integration where a small amplifier package and defined thermal metrics are required.
Recommended supply operation covers 2.7-5.5 V VBAT in internal boost mode and 3-5.5 V VBAT in external boost mode. The VDD supply range is 1.65-1.95 V with 1.8 V nominal operation, while external boost mode supports PVDD from VBAT to 16 V. Speaker requirements include a minimum 3.2 ohm impedance and 10 uH inductance.
Audio performance facts include 5 W output into 8 ohm at 1% THD+N and 6.1 W into 4 ohm at 1% THD+N with VBAT at 3.6 V. The device also specifies 0.01% THD+N at 1 W into 8 ohm, 106.5 dB dynamic range, 112.5 dB SNR, and a 384 kHz average Class-D PWM switching frequency in spread spectrum mode.
