ZTS6554

Hear Aiding MEMS Microphone ZTS6554 DESCRIPTION The ZTS6554 is a high quality, low voltage, low power analog output bottom-ported omni-directional MEMS microphone.ZTS6554 consists of a MEMS microphone element and an preamplifier. ZTS6554 has a high SNR and flat wideband frequency response, resulting in natural sound with high intelligibility. Extra EMI filter for RF noise attenuation is built inside. Due to the built-in filter, ZTS6554 shows high immunity to EMI. The ZTS6554 is available in a thin 3.35mm × 2.50mm × 0.98mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The ZTS6554 is halide free. FEATURES ● Small package ● Flat Frequency Response SNR of 67dBA ● Low Current ● Ultra-Stable Performance ● Standard SMD Reflow ● Omni-directional Pins Configuration and Description Bottom View APPLICATIONS ● Hear Aiding ORDERING INFORMATION PART ZTS6554 RoHS Yes Ship, Quantity Tape and Reel,1K Top Bottom Typical Applications The ZTS6554output can be connected to a codec microphone input or to a high input impedance gain stage. A dc-blocking capacitor is required at the output of the microphone. Note: Connect to Audio DSP All Ground pins must be connected to ground. Capacitors near the microphone should not contain Class 2 dielectrics.
