Customizable smart reset ICs offer safe and convenient reset for wearable devices

The SR1/SR2 smart reset™ ICs provide a full set of functions guaranteeing an escape sequence from OS or application failures by extending the functional capability of the existing buttons. With a programmable delay to avoid accidental resets, these ICs save space and cost for equipment manufacturers, and significantly increase convenience for the user. These devices bring a real value to battery-operated applications such as wearable devices. More

Bring true sound quality in your car

STPA003 is a Class AB power amplifier able to improve car audio listening experience. With a maximum power of 4 x 52 W, minimum driving load of 2 ohm, compatibility with start-stop and hybrid vehicles and extreme robustness against misconnections, the device is suitable for every modern infotainment system. No more concerns about connectivity with mobile devices, since the product’s architecture helps ensure excellent immunity against interference coming from mobile devices (so-called “GSM effect”) without the need for input filtering.

The industry's most flexible and highest-performance integrated RF synthesizer

A single STW81200 wideband RF synthesizer is able to cover frequencies from 46.875 MHz to 6 GHz. With low noise VCOs and an integer and fractional-N PLL architecture for supporting multi-standard SDR applications, the STW81200 also integrates internally broadband matched RF outputs and supports an external crystal oscillator to further reduce the number of external components. The STW81200’s flexible power supply options ensure the best tradeoff between performance and consumption. More

New ultra-compact low-power top-port digital MEMS microphones

MP34DT01-M and MP34DT02 are ST’s newest top-port digital MEMS microphones. The new SMD-compliant, EMI-shielded package make them robust, safe and able to sustain any manufacturing process. In addition to the ultra-compact HCLGA package (3 x 4 x 1.06 mm), common features include low power consumption and omnidirectional sensitivity. An acoustic overload point of 120 dBSPL, -26 dBFS sensitivity and an SNR of 61 dB (60 dB for the MP34DT02) make them an excellent choice for applications such as smartphones, portable devices, VoIP, speech recognition, and A/V eLearning devicesMore
