These two new products were the first results of the acquisition of Oligo in March last year and the first application of Wolfson's AudioPlusTM True Mics technology. Wolfson's technology is based on its unique MEMS sensor intellectual property (IP) with standard CMOS foundry, providing greater stability, repeatability and scalable throughput, bringing cost and flexibility to end users. Sexual benefits. MEMS microphones are capable of withstanding the temperature of reflow soldering technology in surface mount processes and are available with automated placement technology. This eliminates the need for manual inserts for the microphone, reducing assembly time and cost.
The compact WM7110 (4.72 x 3.76 x 1.25mm package size) and ultra-miniature WM7120 (3.76 x 2.95 x 1.10mm package size) chip standard power consumption of 160μA, making it ideal for portable applications, including mobile Telephones, portable media players, digital cameras, video cameras, navigation devices and noise canceling headphones. These two chips provide an improved 62dB A-weighted, reduced microphone background noise, ensuring a more cost-effective, pure and transparent sound capture. The chip also features low total harmonic distortion (THD) with a maximum of 0.5% at 100dB SPL for excellent linearity and flat phase response.
As the first MEMS silicon microphone that delivers +/-1dB of minimal sensitivity error, the upgraded WM7110E and WM7120E chips rewrite multiple microphone design laws while incorporating innovative new applications into cost-effective implementations; The production of online test and calibration software algorithms with minimal +/-1 dB sensitivity error provides a better match for the microphone - a key factor in microphone array beamforming design. By using a more matched microphone, the noise cancellation design can also be significantly improved.
Wolfson, chief technology officer of Wolfson, said, "This new ultra-miniature True Mics MEMS silicon microphone brings Wolfson-quality recordings to a wider range of consumer applications. Through proprietary CMOS/MEMS film technology and +/ With a sensitivity error of 1dB, we bring cost-effective, innovative multi-microphone applications to original equipment manufacturers (OEMs) and original design manufacturers (ODMs)."
As part of the Wolfson AudioPlusTM strategy, these two new silicon microphones are fully compatible with all of the company's audio products, including Wolfson's Enhanced Soundware active noise cancellation technology. Wolfson's new microphones in its portfolio support more components in the audio signal chain.
Supply and price:
Samples of the WM7110 and WM7110E will be available in November, and the WM7120 and WM7120E will be available in December. The WM7110 and WM7120 are priced at $1.64 each in 1,000-piece quantities.
