The proven and evolving design series continues to support high-performance, high-density innovation in such applications as cell phones, smart phones, laptop computers, sensors, digital still cameras, portable music players, and other portable electronic devices. Design variables include ever-smaller sizes, lower profiles and mounting options, increased output capacities, and new digital audio options that eliminate analog noise. For manufacturers, surface mount designs eliminate offline subassembly production costs. Customized designs are supplied on tapeand-reel and can be run through standard automatic pick-n-place equipment during in-line surface mount manufacturing. The microphones can also be integrated with our patented IntelliSonicTM software and special porting designs to provide a precisely customized sound. s MaxRF models eliminate GSM/TDMA burst noise and provide wide-band RF noise suppression s Slim UltraMini footprint - less than 8.5mm 2 (SPQ Series) s Integrated designs with differential and ultrasonic outputs s Zero Height Mic TM for thinnest ever designs Typical RF Performance of Microphone Families -30 -40 -50 Key -60 -70 Sensitivity Standard Enhanced RF MaxRF Noise Floor dBv -80 s MaxRF: Best in class filtering for RF applications; GSM mobile phones, near-antenna designs -90 -100 -110 s Enhanced RF: Good filtering for general RF applications; mobile phones with clean RF designs -120 -130 -140 -150 0.5 0.7 0.9 1.1 1.3 1.5 1.7 1.9 2.1 2.3 Frequency (GHz) 2.5 s Standard: Best for non-RF applications; DSC, MP3, headsets Port Configurations TM Zero Height Mic (Bottom Port) Legacy Standard (Top Port) Device Case 0.5 mm Rubber Gasket Acoustic Port Microphone PCB Bottom port mounting enables minimum PCB-to-case thickness, simple gasket designs, and best-in-class SNR 4 www.knowles.com 1.5 mm MEMS MICROPHONES Part Numbering SPU0410HR5H-PB-7 1 1 Product Description SPY: (3.00 x 1.90) SPQ: (3.76 x 2.24) SPU: (3.76 x 2.95) SPM: (4.72 x 3.76) SPA: (3.35 x 2.50) SPK: (4.00 x 3.00) 2 Series 0406: Differential 0409: Unity Gain 0410: Unity Gain 0414: Amplified 0415: Digital 0423: Digital 0824: Unity Gain 0833: Digital 1410: Unity Gain 1423: Digital 2410: Unity Gain 2 3 Port Hole Type H: Top Port L: Bottom Port 3 4 5 4 RF Filter D: Standard E: Enhanced M: Enhanced R: MAX-RF 6 7 5 Supply Voltage 3: 1.5-5.5V 4: 1.6-3.6V 5: 1.5-3.6V 8 6 Halogen Free 7 Version Knowles Internal (Reference Only) 8 Packaging QTY Product Specific (Reference Only) Top Port Analog t416BOE412 MFTTUIBONN 2 GPPUQSJOUTBSFJEFBMGPSNVMUJQMF NJDSPQIPOFBQQMJDBUJPOT t.BY3'UFDIOPMPHZQSPWJEFTXJEFCBOEOPJTFTVQQSFTTJPO GPSDPNQBDUEFWJDFTXJUIDIBMMFOHJOHSPVUJOHBOEMBZPVUT t"MM4J4POJDTMNJDSPQIPOFTBSFEFTJHOFEXJUIMFBEJOHFEHF.&.4 UFDIOPMPHZGPSTUBCMFBDPVTUJDQFSGPSNBODFVOEFSFYUSFNF DPOEJUJPOTTVDIBTIJHIUFNQFSBUVSF TIPDL BOEWJCSBUJPO Model Description Size (mm) Supply Voltage (min-max) RF Immunity Sensitivity @1kHz (dBV/Pa) Output Impedance (Ohms) Maximum Current Drain (mA) SPQ0410HR5H Unity Gain 3.76 x 2.24 x 1.10 1.5 to 3.6v MaxRF -42.0 <400 <0.25 SPQ2410HR5H Unity Gain 3.76 x 2.24 x 1.10 1.5 to 3.6v MaxRF -42.0 <400 <0.25 SPU0409HD5H Unity Gain 3.76 x 2.95 x 0.90 1.5 to 3.6v Standard -42.0 <100 <0.19 SPU0410HR5H Unity Gain 3.76 x 2.95 x 1.10 1.5 to 3.6v MaxRF -42.0 <400 <0.16 SPU0414HR5H Amplified 3.76 x 2.95 x 1.10 1.5 to 3.6v MaxRF -22.0 <400 <0.22 SPUL409HE5H Unity Gain 3.76 x 2.95 x 1.10 1.5 to 3.6v Enhanced -42.0 <300 <0.19 Note: All performance curves are typical www.knowles.com 5 MEMS MICROPHONES Bottom Analog t416BOE41" MFTTUIBONN 2 GPPUQSJOUTBSFJEFBMGPS NVMUJQMFNJDSPQIPOFBQQMJDBUJPOT t4J4POJDTM;FSP)FJHIU.JDTMTISJOLTQSPEVDUUIJDLOFTT CZVQUP t.JOJNJ[FTUIFEJTUBODFCFUXFFO1$#BOEEFWJDFIPVTJOH t&OBCMFTUIFUIJOOFTU IJHIFTUEFOTJUZQSPEVDUEFTJHOT Sensitivity @1kHz (dBV/Pa) Output Impedance (Ohms) Maximum Current Drain (mA) MaxRF -38.0 <400 <0.16 1.5 to 3.6v MaxRF -38.0 <400 <0.25 1.5 to 3.6v Enhanced -38.0 <200 <0.25 Model Description Size (mm) Supply Voltage (min-max) SPY0824LR5H Unity Gain 3.00 x 1.9 x 0.90 1.5 to 3.6v SPA2410LR5H Unity Gain 3.35 x 2.50 x 0.98 SPU0409LE5H Unity Gain 3.76 x 3.00 x 1.10 RF Immunity SPU0410LR5H* Unity Gain 3.76 x 3.00 x 1.10 1.5 to 3.6v MaxRF -38.0 <400 <0.25 SPU1410LR5H Unity Gain 3.76 x 3.00 x 1.10 1.5 to 3.6v MaxRF -38.0 <400 <0.25 SPM0406HE3H Differential 4.72 x 3.76 x 1.25 1.5 to 5.5v Enhanced -22.0 <500 <0.50 *Extended frequency response for ultrasonic applications Digital t)FMQTSFEVDFTZTUFNOPJTFPOBVEJPTJHOBMMJOFT t&BTJFS GBTUFSUPSPVUFBOEMBZPVUEJHJUBMUSBDFTXJUIPVU TJHOBMDPSSVQUJPO t%JHJUBM1%. 1VMTF%FOTJUZ.PEVMBUJPO PVUQVUBWBJMBCMF XJUIJOUFHSBUFETMFFQNPEFBOEDPNQBUJCMFXJUITUFSFP JOQVUBQQMJDBUJPOT 6 Model Description Size (mm) Supply Voltage (min-max) RF Immunity Sensitivity (dBFS/Pa) Output Impedance (Ohms) Maximum Current Drain (mA) SPK0833LM4H Digital 4.00 x 3.00 x 1.00 1.6 to 3.6v Digital MaxRF -26.0 160pf Maximum Load <0.70 SPK0415HM4H Digital 4.00 x 3.00 x 1.06 1.6 to 3.6v Digital Enhanced -26.0 100pf Maximum Load <0.65 SPM0423HD4H Digital 4.72 x 3.76 x 1.25 1.6 to 3.6v Digital Standard -26.0 100pf Maximum Load <0.60 SPM0423HE4H Digital 4.72 x 3.76 x 1.25 1.6 to 3.6v Digital Enhanced -26.0 100pf Maximum Load <0.60 SPM0423HM4H Digital 4.72 x 3.76 x 1.25 1.6 to 3.6v Digital Enhanced -26.0 100pf Maximum Load <0.60 SPM1423HM4H Digital 4.72 x 3.76 x 1.25 1.6 to 3.6v MaxRF -22.0 100pf Maximum Load <0.60 www.knowles.com Note: All performance curves are typical DYNAMIC SPEAKERS Dynamic Speakers Knowles dynamic speakers are designed to maximize space efficiency and provide superior audio performance for voice and music in small, slim consumer devices, such as mobile handsets or smartphones.

Knowles is the only supplier who offers this specific technology for miniaturized speaker systems. N`BassTM is a special material which increases the back volume seen by the speaker by up to 100% thus enabling either a better acoustic performance - specifically more bass - or smaller speaker box designs. It also enables the usage of bigger speakers with the same gross application volume. The N`BassTM material has no negative influence on antenna performance compared to conventional materials.

Sound pressure causes the diaphragm to vibrate relative to the backplate creating a variable voltage. The ASIC buffers the resulting signal for external electrical connection. For digital SiSonic microphones, the microphone accepts a clock signal and converts the output to a synchronus PDM data format. SiSonic microphones are designed for surface mount (SMT) attach. The sensitivity of analog SiSonic microphones is measured in units of dBV relative to 1.0 Pascal while digital microphone sensitivity is measured in dBFS relative to 1.0 Pascal. A charge pump in the ASIC provides a constant bias voltage to the diaphragm of the MEMS when the microphone is powered. This bias voltage does not degrade with time, temperature, or humidity. In conjunction with the floating diaphragm construction of the MEMS which is fabricated in standard silicon wafer processes, SiSonic microphones yield constant sensitivity distributions over a wide operating temperature range and after multiple reflow passes.

Inside a Knowles microphone is a thin flexible diaphragm, an electrically charged plate, and an amplifier (Fig. 3). The output voltage is proportional to changes in the small separation between the diaphragm and the charged plate (Fig. 4). As sound pressure inside the front cavity increases, the diaphragm is pushed closer to the plate. As the pressure decreases, it moves further away. The motion of the diaphragm produces a small electrical signal that is amplified by a miniature circuit inside the microphone. The sensitivity of a typical Knowles' microphone is measured in units of dB relative to 1 Volt per 0.1 Pascal.

A cross section of a typical Knowles speaker is shown in Fig. 5. The basic components of the speaker are: a coil of wire, a metal U-shaped reed called the armature, a pair of permanent magnets, a drive rod, and a diaphragm. The coil and armature act as an electromagnet. An alternating current in the coil causes the polarity of the armature to switch back and forth from north to south. The free end of the armature bends slightly up and down as it is attracted alternately to the top and bottom magnets (Fig. 6). The diaphragm, pulled along by the drive rod, pumps air in and out of the speaker. The mechanical motion of the armature is thus converted into sound. The sound output of a typical Knowles' speaker is measured in units of dB SPL (sound pressure level) relative to 20 Pa.
