Stereo Class-D amplifier features an integrated audio processor

07-04-2022 | Mouser Electronics | Semiconductors

Texas Instruments TAS5828M 50W Stereo Class-D Amplifier, available now from Mouser, is a stereo high-performance, closed-loop Class-D with an integrated audio processor with up to 192kHz architecture. After startup with Software Control Mode, the device implements classic BQs, three-band DRC, AGL, and a proprietary algorithm called HybridPro. The Hybrid-Pro algorithm detects the upcoming audio power demand and supplies a PWM format control signal for the former DC-DC converter through the Hybrid-Pro feedback pin. The device supports up to 4ms of delay buffer of the audio signal for predictable envelop tracking, which assists in preventing audio clipping due to DC-DC voltage adjustment.

While setting into Hardware control mode, it supports switching frequency, BTL/PBTL mode, analog gain, and cycle by cycle current limit threshold through pin configuration. This mode is particularly designed to eradicate end system software driver integration efforts.

Typical applications include battery-powered speakers, wireless, Bluetooh speakers, soundbars and subwoofers, and heat or efficiency sensitive audio systems.
