The new EMIF06-AUD01F2 from STMicroelectronics implements complete EMI filtering and ESD protection for all handset speaker and microphone channels. The EMIF06-AUD01F2 eliminates audible handset demodulation noise by achieving -25 dB attenuation through the stop-band 800 – 2480 MHz, using high density 1.3-nF PZT (lead, zirconate titanate) capacitors on the microphone lines. It also achieves high ESD suppression through the combination of integrated TVS (transient voltage suppressor) diodes, low-inductance packaging, and the Z-R-Z pi filter. By combining both filtering and ESD protection for handset speaker and microphone channels, the EMIF06-AUD1F2 reduces board space used by 50 percent as compared to previous integrated solutions using two ICs.
