The STA381BWTR by TST is a Sound Terminal® 2.1-channel high-efficiency digital audio system designed for versatile audio applications. It operates within a wide supply voltage range from 4.5 V to 26 V, with an absolute maximum rating of 30 V. The device supports I2C control with selectable addresses and offers embedded IC protection, including short-circuit, thermal, overcurrent, and undervoltage protection.
This audio system IC features an I2S interface with a sampling rate from 32 kHz to 192 kHz and supports three output power stage configurations: 2.0 mode (L/R full bridges), 2.1 mode (L/R two half-bridges, subwoofer full bridge), or 2.1 mode (L/R full bridges, PWM output for external subwoofer amplifier). It can drive loads up to 2 x 20 W into 8 Ω or a combination of 2 x 9 W into 4 Ω plus 1 x 20 W into 8 Ω.
Additional features include a 100 dB dynamic range, embedded RMS meter, selectable headphone/line out drivers, and a programmable noise-gating function. The headphone output can drive 40 mW into 32 Ω, while the line output offers 2 Vrms capability. The STA381BWTR also provides extensive audio processing capabilities, including up to 12 user-programmable biquads, independent DRCs, digital gain control from +48 dB to -80 dB, and soft volume updates. It is available in a VQFN48 package.
The STA381BWTR is suitable for various audio systems requiring high efficiency and flexible configuration. Its comprehensive protection features and advanced audio processing make it a robust choice for demanding applications. The device is available in Tray or Tape and Reel packaging.
