High fidelity audio apps excel with MUS-IC D/A converters
ROHM has launched a new branding “MUS-IC” reflecting ROHM’s focus on solutions for high-fidelity audio products. This branding covers a range of D/A converter ICs (DAC ICs), optimized for high-fidelity reproduction, and power supply products. The increased adoption of high-resolution audio sources has lately strengthened the demand for audio equipment that can deliver an appropriate sound […]
Filters suppress noise from 600 MHz to 2.7 GHz on audio lines
TDK Corporation has expanded the MAF1005G series of noise suppression filters for audio lines with four new MAF1005GAD-D types, which, thanks to their low DC resistance, feature a high rated current of up to 1.25 A. The new types employ TDK’s proprietary low-distortion ferrite that enables the new components to suppress noise at cellular frequencies from […]
Active noise cancellation, Part 2: Implementation
Part 1 of this FAQ looked at the basic concept of active noise cancellation, how it might be implemented in principle using analog circuitry, and the harsh reality of actually providing the ANC function. Part 2 looks at modern ANC systems and how they function, as well as their practical issues. Q: Is ANC using […]
Piezo ceramic harsh environment speaker features extended frequency range
Announced today by ISL Products International Ltd the PZ-94 harsh environment piezoelectric loudspeaker for broad frequency range applications. Ultra-thin, small, and lightweight, the piezo ceramic loudspeaker may be driven by low power. The speaker reproduces voice in the frequency response range of 450 HZ to 20 kHZ, and is tested to MIL–STD–810, method 509.1 (salt fog). The PZ-94 loudspeaker system features a […]
PCIe Gen 4-compliant clock buffers powered from single 1.5 V/1.8 V supplies
Silicon Labs has introduced a new family of low-power PCI Express (PCIe) Gen 1/2/3/4 clock buffers that provide ultra-low jitter clock distribution in 1.5 V and 1.8 V applications. With additive jitter performance of 40 fs RMS (typical), Silicon Labs’ new Si532xx PCIe clock buffers provide more than 90 percent margin to stringent PCIe Gen 3 […]
