GENERAL DESCRIPTION
The ADMP4411 is a high performance, low power, digital output,
omnidirectional MEMS microphone with a bottom port. The
complete ADMP441 solution consists of a MEMS sensor, signal
conditioning, an analog-to-digital converter, antialiasing filters,
power management, and an industry standard 24-bit IS inter-
face. The IS interface allows the ADMP441 to connect directly
to digital processors, such as DSPs and microcontrollers, with-
out the need for an audio codec in the system.
The ADMP441 has a high SNR and high sensitivity, making it
an excellent choice for far field applications. The ADMP441 has
a flat wideband frequency response, resulting in natural sound
with high intelligibility.
The ADMP441 is available in a thin 4.72 mm × 3.76 mm ×
1 mm surface-mount package. It is reflow solder compatible
with no sensitivity degradation. The ADMP441 is halide free.
