ZTS6211E
Wideband MEMS Microphone with Top Port and Analog Output
DESCRIPTION
The ZTS6211E is a high quality, low cost, low power
analog output top-ported omni-directional MEMS
microphone. ZTS6211E consists of a MEMS microphone
element and an preamplifier. ZTS6211E 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, ZTS6211E shows high immunity to EMI.
The ZTS6211E is available in a thin 3.76mm × 2.95mm ×
1.1mm surface-mount package. It is reflow solder
compatible with no sensitivity degradation. The
ZTS6211E is halide free.

the device. This is a stress only rating and operation of
the device at these or any other conditions above those
indicated in the operational sections of this specification
is not implied.
Electro-Static Discharge Sensitivity
This integrated circuit can be damaged by ESD.
It is recommended that all integrated circuits
be handled with proper precautions. Failure
to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete device failure.
