The STA381BWTR from STMicroelectronics is a Sound Terminal® 2.1-channel high-efficiency digital audio system processor. It is designed for audio applications and features a wide operating supply voltage range from 4.5 V to 26 V, with an absolute maximum rating of 30 V. The device supports I²C and I²S interfaces for control and audio data transmission, with sampling rates from 32 kHz to 192 kHz.
This IC offers flexible output power stage configurations, including 2.0 mode with L/R full bridges, and 2.1 mode with L/R two half-bridges and a subwoofer full bridge, or L/R full bridges with PWM output for an external subwoofer amplifier. It can drive loads up to 2 x 20 W into 8 Ω. Embedded protection features include short-circuit, thermal, overcurrent, and undervoltage protection.
The STA381BWTR is housed in a 48-VQFN (7x7 mm) package and is available in Tape and Reel or Tray packaging. It supports surface mount mounting type. The device includes features like an embedded RMS meter for loudness measurement, selectable headphone/line out drivers, and programmable biquads for audio processing.
Key electrical characteristics include a 1 Vrms stereo analog input, 2 Vrms line output capability, and headphone output capability of 40 mW into 32 Ω. Digital gain and attenuation range from +48 dB to -80 dB with 0.125 dB/step resolution. It also features independent DRCs configurable as dual-band anticlippers or limiters/compressors.
