GENERAL DESCRIPTION
The ADMP421 is a high performance, low power, digital output
bottom-ported omnidirectional MEMS microphone. The
ADMP421 consists of a MEMS microphone element and an
impedance converter amplifier followed by a fourth-order Σ-Δ
modulator. The digital interface allows for the pulse density
modulated (PDM) output of two microphones to be time-
multiplexed on a single data line using a single clock.
The ADMP421 has a high SNR and high sensitivity, making it
an excellent choice for far field applications. The ADMP421 has
a flat wideband frequency response, resulting in natural sound
with high intelligibility. Low current consumption and a sleep
mode enable long battery life for portable applications. A built-
in particle filter provides high reliability. The ADMP421 complies
with the TIA-920 Telecommunications Telephone Terminal
Equipment Transmission Requirements for Wideband Digital
Wireline Telephones standard.
The ADMP421 is available in a thin 3 mm × 4 mm × 1 mm
surface-mount package. It is reflow solder compatible with no
sensitivity degradation. The ADMP421 is halide free.
