3 Description
The TAS6511-Q1 is a mono-channel, digital-input,
Class-D audio amplifier that supports 2MHz switching
frequency enabling a cost and size-optimized singlechannel
audio amplifier design. The device operates
from 4.5V to 19V and delivers up to 28W (14.4V,
4Ω, 10% THD+N) and up to 50W (14.4V, 2Ω, 10%
THD+N). The device integrates DC and AC load
diagnostics to determine the status of the connected
load before enabling the output stage. Additionally,
the device can monitor the output load condition while
in PLAY mode with or without audio using real-time
load diagnostics which operates independently from
the host and audio input.
TAS6511-Q1 can monitor the output current, PVDD
voltage, and temperature of the device and can
report this data through TDM or I2S. The integrated
DSP of the TAS6511-Q1 enables advanced protection
features such as PVDD foldback, thermal foldback,
and Speaker Guard™ Pro power limiter. The DSP
also enables an additional low-latency signal path,
providing up to 70% faster signal processing at 48kHz
for time-sensitive Active Noise Cancellation (ANC)
and Road Noise Cancellation (RNC) applications.
The device is available in a small pad-down TSSOP
package, enabling a heatsink-free audio amplifier
design.
