I2S, LJ, RJ, 4 to 16-channel TDM input

SDOUT is used to implement audio monitoring, sub-channels or echo cancellation

Supports three-wire digital audio interface (no MCLK required)

High-efficiency Class D modulation

>90% power supply efficiency, 70mΩ RDSon

Outstanding audio performance

THD+N ≤ 0.03% (1 W, 1 kHz, PVDD = 12 V)

SNR ≥ 110dB (A-weighted), ICN ≤ 40μVrms

Flexible processing features

3-band advanced DRC+2 EQs +AGL+2 EQs

Each channel has 12 BQS and level meters

Mixer, volume, dynamic EQ, output crossover

PVDD detection and H-class algorithm audio signal tracking

Flexible power supply configuration

4.5V to 26.4V PVDD

1.8V or 3.3V DVDD and I/O

Outstanding integrated self-protection

Overcurrent error (OCE

Cycle-by-cycle current limiting supports four optional OC levels

Overheat Warning (OTW

Overheating error (OTE

Under-voltage and over-voltage lockout (UVLO/OVLO)

PVDD voltage drop detection

Easy system integration

I2C software control (TAS5827 supports fast and fast enhancement modes) or hardware mode

Compared with open-loop devices, fewer passive devices are required

For details

The TAS5827RHBR is a high-performance closed-loop D-stage stereo amplifier with an integrated audio processor that supports audio up to 192kHz.

When the device is set to hardware control mode, the TAS5827RHBR supports the selection of switching frequency, analog gain, BTL/PBTL mode and cycle-by-cycle current limit threshold through pin configuration. This mode is specifically designed to eliminate the need for integrating terminal system software drivers.
