WM7133LIMS/RV

WM7133L w Bottom Port Analogue Silicon Microphone DESCRIPTION FEATURES The WM7133L is a low-profile silicon analogue microphone. It offers high Signal to Noise Ratio (SNR) and low power consumption and is suited to a wide variety of consumer applications.   High SNR (64.5dB) Low variation in sensitivity (±3dB)   Low current consumption (180µA) Analogue output The WM7133L incorporates Wolfson’s proprietary CMOS/MEMS membrane technology, offering high reliability and high performance in a miniature, low-profile package. The WM7133L is designed to withstand the high temperatures associated with automated flow solder assembly processes. (Note that conventional microphones can be damaged by this process.)   Bottom Port LGA Package 1.5V to 3.7V supply BLOCK DIAGRAM APPLICATIONS   Mobile phone handsets Wearable devices   Portable media players Digital cameras 3D VIEW 3.35mm x 2.50mm x 0.98mm LGA package WOLFSON MICROELECTRONICS plc Pre-Production, May 2014, Rev 3.1 Copyright  2014 Wolfson Microelectronics plc WM7133L Pre-Production TABLE OF CONTENTS DESCRIPTION ................................................................................................................ 1  FEATURES ..................................................................................................................... 1  APPLICATIONS.............................................................................................................. 1  BLOCK DIAGRAM ......................................................................................................... 1  3D VIEW ......................................................................................................................... 1  TABLE OF CONTENTS .................................................................................................. 2  PIN CONFIGURATION ................................................................................................... 3  PIN DESCRIPTION ......................................................................................................... 3  ORDERING INFORMATION ........................................................................................... 3  ABSOLUTE MAXIMUM RATINGS ................................................................................. 4  IMPORTANT ASSEMBLY GUIDELINES ....................................................................... 4  RECOMMENDED OPERATING CONDITIONS .............................................................. 4  ACOUSTIC AND ELECTRICAL CHARACTERISTICS .................................................. 5  TERMINOLOGY ......................................................................................................................... 5  TYPICAL PERFORMANCE ............................................................................................ 6  APPLICATIONS INFORMATION ................................................................................... 7  RECOMMENDED EXTERNAL COMPONENTS ........................................................................ 7  OPTIMISED SYSTEM RF DESIGN ........................................................................................... 7  CONNECTION TO A WOLFSON AUDIO CODEC .................................................................... 8  PCB LAND PATTERN AND PASTE STENCIL .......................................................................... 9  PACKAGE DIMENSIONS ............................................................................................. 10  IMPORTANT NOTICE .................................................................................................. 11  ADDRESS: ............................................................................................................................... 11  REVISION HISTORY .................................................................................................... 12  w PP, May 2014, Rev 3.1 2 WM7133L Pre-Production PIN CONFIGURATION PIN DESCRIPTION PIN NAME TYPE DESCRIPTION 1 VDD Supply 2 OUTPUT Analogue Output Analogue supply 3 GND Supply Microphone analogue output signal Analogue ground ORDERING INFORMATION DEVICE DESCRIPTION TEMPERATURE RANGE WM7133LIMS/RV Standard (tape and reel) -40 to +100 C o MOISTURE SENSITIVITY LEVEL PEAK SOLDERING TEMPERATURE MSL2A +260 C o Note: Reel quantity = 5000 All devices are Pb-free and Halogen free. w PP, May 2014, Rev 3.1 3 WM7133L Pre-Production ABSOLUTE MAXIMUM RATINGS Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test conditions specified. ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible to damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage of this device. Wolfson tests its package types according to IPC/JEDEC J-STD-020 for Moisture Sensitivity to determine acceptable storage conditions prior to surface mount assembly. These levels are: MSL1 = unlimited floor life at
