GENERAL DESCRIPTION
The ADMP5211 is a high performance, ultralow noise, low
power, digital output, bottom-ported omnidirectional MEMS
microphone. The ADMP521 consists of a MEMS microphone
element and an impedance converter amplifier followed by a
fourth-order sigma-delta (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 ADMP521 is function and pin compatible with
the ADMP421 microphone, providing an easy upgrade path.
The ADMP521 has a very high signal-to-noise ratio (SNR) and
common sensitivity of 26 dBFS, making it an excellent choice
for far field applications. The ADMP521 has an extended wide-
band frequency response resulting in natural sound with high
intelligibility. Low current consumption and a sleep mode with
less than 1 A current consumption enables long battery life
for portable applications. The ADMP521 complies with the
TIA-920 Tele-communications Telephone Terminal Equipment
Transmission Requirements for Wideband Digital Wireline
Telephones standard.
The ADMP521 is available in a thin 4 mm × 3 mm × 1 mm
surface-mount package. It is reflow solder compatible with
no sensitivity degradation. The ADMP521 is halide free.
