Pulse Density Modulation microphone features super-wide dynamic range
TDK announces the T5818 Pulse Density Modulation (PDM) microphone with a dynamic range of 107dB at 590µA, the widest dynamic range in the industry at the lowest power. This allows for excellent acoustic performance in environments that shift from very quiet to very loud, such as far-field voice pickup barge-in for Smart Speaker applications. The T5818 microphone features 66dBA SNR, 135dB […]
Lead-free chip resistor networks designed for RoHS compatibility
TT Electronics announced the latest series in its Green Thick-Film chip portfolio – the GBCN, a thick-film chip array that is completely free of Pb (lead) and its compounds. As environmental regulations become increasingly stringent, the new GBCN series deliver peace of mind through exemption-free RoHS compliance. These resistors meet growing industry demand for pull-up, […]
MEMS-based absolute pressure sensors target altimeter apps
Würth Elektronik presents a very compact MEMS-based (Micro-Electro-Mechanical Systems) absolute pressure sensor: The 2.0 x 2.0 x 0.8 mm sized WSEN-PADS measures pressure in the range between 26 and 126 kPa. Its output data rate can be selected between 1 and 200 Hz. The sensor contains an ASIC (application-specific integrated circuit) and a temperature sensor. […]
What are MEMS microphone arrays?
Beamforming arrays let designers create directional microphones using MEMS devices. With the right signal processing algorithms, these can enhance the user experience delivered by many types of audio equipment. An array can be simple, comprising as few as two microphones, and can be arranged in various configurations depending on the expected location of the preferred […]
RF Switches, Part 2: Analog and MEMS switches
Part 1 of this FAQ looked at the venerable electromechanical RF switch – still widely used in some applications, where it is the only viable option – and use of PIN diodes as RF switches. This part looks at analog and MEMS-based switches. Q: What is an analog switch? A: It’s conceptually straightforward: in basic […]
MEMS inertial accelerometer now offered in ±10 g and ±50 g ranges
Silicon Designs, Inc. announced that additional new g-ranges and end-user enhancements have been added to its Model 2227 MEMS inertial accelerometer series. Initially launched in October 2018 as a strictly ±25-g product, the Series is now offered in both ±10 g and ±50 g ranges, respectively. Stock quantities of all three models are immediately available […]
