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 I²S interface. The I²S interface allows the ADMP441 to connect directly
to digital processors, such as DSPs and microcontrollers, without the need for an audio codec in the system.
1
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.

ADMP441
Data Sheet
THEORY OF OPERATION
The ADMP441 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 I²S interface.
The ADMP441 complies with the TIA-920 Telecommunications
Telephone Terminal Equipment Transmission Requirements for
Wideband Digital Wireline Telephones standard.
UNDERSTANDING SENSITIVITY
The casual user of digital microphones may have difficulty
understanding the sensitivity specification. Unlike an analog
microphone (whose specification is easily confirmed with an
oscilloscope), the digital microphone output has no obvious
unit of measure.
It is not recommended to supply active clocks (WS and SCK) to
the ADMP441 while there is no power supplied to VDD. Doing
this continuously turns on ESD protection diodes, which may
affect long-term reliability of the microphone.
I²S DATA INTERFACE
The slave serial data port’s format is I²S, 24-bit, twos complement. There must be 64 SCK cycles in each WS stereo frame, or
32 SCK cycles per data-word. The L/R control pin determines
whether the ADMP441 outputs data in the left or right channel.
For a stereo application, the SD pins of the left and right
ADMP441 microphones should be tied together as shown in
Figure 9. The format of a stereo I²S data stream is shown in
Figure 10. Figure 11 and Figure 12 show the formats of a mono
microphone data stream for left and right microphones,
respectively.
Data Output Mode
The output data pin (SD) is tristated when it is not actively
driving I²S output data. SD immediately tristates after the LSB
is output so that another microphone can drive the common
data line.
POWER MANAGEMENT
The ADMP441 has three different power states: normal
operation, standby mode, and power-down mode.
Normal Operation
The microphone becomes operational 218 clock cycles (85 ms
with SCK at 3.072 MHz) after initial power-up. The CHIPEN
pin then controls the power modes. The part is in normal operation mode when SCK is active and the CHIPEN pin is high.
The ADMP441 should not be transitioned from standby to
power-down mode, or vice versa. Standby mode is only
intended to be entered from the normal operation state.
It always takes 217 clock cycles to restart the ADMP441 after VDD
is applied.
The microphones have zero output for the first 218 SCK clock
cycles (85 ms with SCK at 3.072 MHz) following power-up.
Although the industry uses a standard specification of 94 dB
SPL, the ADMP441 test method applies a 104 dB SPL signal.
The higher sound pressure level reduces noise and improves
repeatability. The ADMP441 has excellent gain linearity, and
the sensitivity test result at 94 dB is derived with very high
confidence from the test data.
The microphone enters standby mode when the serial data
clock SCK stops and CHIPEN is high. Normal operation
resumes 214 clock cycles (5 ms with SCK at 3.072 MHz) after
SCK restarts.
The microphone enters power-down mode when CHIPEN is
low, regardless of the SCK operation. Normal mode operation
resumes 217 SCK clock cycles (43 ms with SCK at 3.072 MHz)
after CHIPEN returns high while SCK is active.
STARTUP
The ADMP441 has a nominal sensitivity of −26 dBFS at 1 kHz
with an applied sound pressure level of 94 dB. The units are in
decibels referred to full scale. The ADMP441 default full-scale
peak output word is 223 – 1 (integer representation), and
−26 dBFS of that scale is (223 − 1) × 10(−26/20) = 420,426. A pure
acoustic tone at 1 kHz having a 1 Pa rms amplitude results in an
output digital signal whose peak amplitude is 420,426.
Standby Mode
Power-Down Mode
The SD trace should have a pull-down resistor to discharge the
line during the time that all microphones on the bus have
tristated their outputs. A 100 kΩ resistor is sufficient for this, as
shown in Figure 9.
Data-Word Length
The output data-word length is 24 bits per channel. The
ADMP441 must always have 64 clock cycles for every stereo
data-word (fSCK = 64 × fWS).
Data-Word Format
The default data format is I²S (twos complement), MSB-first. In
this format, the MSB of each word is delayed by one SCK cycle
from the start of each half-frame.

DIGITAL FILTER CHARACTERISTICS
wide dynamic range. However, it does require a good quality
low-pass filter to eliminate the high frequency noise.
The ADMP441 has an internal digital band-pass filter. A
high-pass filter eliminates unwanted low frequency signals.
A low-pass filter allows the user to scale the pass band with
the sampling frequency as well as perform required noise
reduction.
High-Pass Filter
The ADMP441 incorporates a high-pass filter to remove unwanted
dc and very low frequency components. Table 7 shows the highpass characteristics for a nominal sampling rate of 48 kHz. The
cutoff frequency scales with changes in sampling rate.
Figure 13 shows the response of this digital low-pass filter
included in the microphone. The pass band of the filter extends
to 0.423 × fS and, in that band, has an unnoticeable 0.04 dB of
ripple. The high frequency cutoff of −6 dB occurs at 0.5 × fS. A
48 kHz sampling rate results in a pass band of 20.3 kHz and a
half amplitude corner at 24 kHz; the stop-band attenuation of
the filter is greater than 60 dB. Note that these filter specifications scale with sampling frequency.

APPLICATIONS INFORMATION
POWER SUPPLY DECOUPLING
Reflow Solder
For best performance and to avoid potential parasitic artifacts,
placing a 0.1 µF ceramic type X7R or better capacitor between
Pin 7 (VDD) and ground is strongly recommended. The
capacitor should be placed as close to Pin 7 as possible.
For best results, the soldering profile should be in accordance
with the recommendations of the manufacturer of the solder
paste used to attach the MEMS microphone to the PCB. It is
recommended that the solder reflow profile does not exceed the
limit conditions specified in Figure 4 and Table 5.
The connections to each side of the capacitor should be as short
as possible, and the trace should stay on a single layer with no
vias. For maximum effectiveness, locate the capacitor equidistant
from the power and ground pins or, when equidistant placement
is not possible, slightly closer to the power pin. Thermal connections to the ground planes should be made on the far side of the
capacitor, as shown in Figure 14.

HANDLING INSTRUCTIONS
Pick-and-Place Equipment
The MEMS microphone can be handled using standard pickand-place and chip shooting equipment. Care should be taken
to avoid damage to the MEMS microphone structure as follows:
•
•
•
Use a standard pickup tool to handle the microphone.
Because the microphone hole is on the bottom of the
package, the pickup tool can make contact with any part
of the lid surface.
Do not pick up the microphone with a vacuum tool that
makes contact with the bottom side of the microphone.
Do not pull air out of or blow air into the microphone port.
Do not use excessive force to place the microphone on
the PCB.
