Key Features
The TAS2563 is a digital input Class-D audio amplifier
optimized for efficiently driving high peak power into
small loudspeakers. The Class-D amplifier is capable
of delivering 6.1 W of peak power into a 4 Ω load at
battery voltage of 3.6 V using the integrated 11.5V
Class-H boost, or 10W peak power into 4Ω load in
boost bypass mode using external 12V supply.
– 11.5V, 12-step Look-ahead Class-H boost
– Integrated DSP for speaker protection and
audio processing
– Full Scale Ultrasonic Output to 40kHz
– 2 PDM Microphone inputs
Powerful Class-D audio amplifier :
– 6.1-W 1% THD+N (4 Ω, 3.6 V)
– 5-W 1% THD+N (8 Ω, 3.6 V)
– 10-W 1% THD+N (4 Ω, 12 V)
Advanced Audio Processing
•
•
An on-chip, low-latency DSP supports Texas
Instruments SmartAmp speaker protection algorithms.
The integrated current and voltage sense provide for
real-time monitoring of the loudspeakers, which
permits pushing peak sound pressure levels (SPL)
while keeping speakers from being damaged.
– Dedicated Real-time DSP with:
•
•
•
Real-time I/V-sense Speaker Protection
Short and Open Load Protection
Speaker Thermal and Over Current
Protection
3-band equalization
Psychoacoustic bass
The integrated look-ahead Class-H boost dynamically
adjusts boost voltage during playback, increasing
efficiency and saving battery life in battery-powered
systems. For regulated wall-powered systems,
TAS2563 also features a boost bypass mode,
supporting supply voltages of up to 16V for even
higher output power.

Flexible Interfaces and Control :
– I2S/TDM: 8 Channels of 32 bit up to 96 KSPS
– I2C: Selectable Addresses with Fast Mode+
Support
– Inter-Chp Communication Bus (DSBGA
package)
Two PDM microphone inputs simplify audio signal
chain for two-way audio systems, interfacing digital
microphones with the host processor. A battery
tracking peak voltage limiter with brown-out protection
prevents systems shutdowns by optimizing amplifier
headroom over the entire charge cycle.
– 8 kHz to 96 kHz Sample Rates
Power Efficiency and Flexibility :
– 83.5% Efficiency at 1W
– <1uA HW shutdown VBAT current
– Boost-bypass mode
