GENERAL DESCRIPTION

The ADMP521¹is 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.

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 µA 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.

The ADMP521 has a very high signal-to-noise ratio (SNR) and

common sensitivity of −26 dBFS, making it an excellent choice
