TAS5727PHPR

The Texas Instruments TAS5727PHPR is an active, open-loop Class-D audio amplifier designed for high-fidelity sound reproduction. It delivers 25W of output power and operates from a wide power stage supply voltage range of 8 V to 26 V, making it suitable for various audio applications.

This amplifier features a digital audio input and supports stereo speaker channels. Key integrated features include speaker equalization (EQ) for improved audio performance and dynamic range compression (DRC) for speaker protection and optimized listening modes. The device operates with an analog supply voltage between 3 V and 3.6 V and supports load impedances as low as 4 Ω.

Designed for efficient operation, the TAS5727PHPR boasts up to 90% efficiency, minimizing heat dissipation and potentially eliminating the need for external heatsinks. It supports sample rates from 44.1 kHz to 48 kHz and offers an impressive 106-dB SNR (A-weighted). The amplifier is housed in a 48-pin HTQFP package, measuring 81 mm² (9 mm × 9 mm), and is designed for surface mounting.

Control is managed via an I2C serial interface, and the device operates without an external MCLK. It includes features like independent channel volume control, programmable biquads for audio processing, and automatic sample-rate detection, simplifying integration into audio systems.
