SoundTerminal processor/power-amplifier IC from ST for home audio/video apps

ST Micro has announced that its STA370BWS, a new SoundTerminal processor/power-amplifier chip that employs ST's Full Flexible Amplifier (FFX) technology to deliver high-quality stereo audio at 10W and above, and suitable for consumer applications such as thin LED-backlit Flat TVs.

The key features of the STA370BWS IC are,

Operating input voltage ranges from 7.0 V to 21.5 V
FFX with 100-dB SNR and dynamic range
I2S input data interface
Input and output channel mapping
Programmable zero-detect mute
Automatic invalid input-detect mute
Up to 8 user-programmable biquads/channel
Full short-circuit protection at device power-up

STA370BWS performs a short-circuit check at power on, which increases application safety and prevents pc-board damage, to minimum rework costs for equipment manufacturers. STA370BWS has on-chip power amplifier.

ST Micro says, it's F3X technology, the third-generation of FFX amplifiers, used in the STA370BWS's auxiliary output, improves audio quality by suppressing non-audio signals, such as the carrier waveform that governs the amplifier's timing, to produce clearer, purer sound throughout the output-power range.

Price: Resale price at $2.50 for 10k pieces
Availability: Now in samples
