Maxim Integrated Products introduces the MAX9796 2.3W, Class D audio subsystem. This device combines a high-efficiency, mono Class D amplifier; a DirectDrive stereo headphone amplifier; and a DirectDrive mono receiver amplifier. The device utilizes the company's active-emissions-limiting (AEL) circuitry and spread-spectrum-modulation technique, which reduce EMI and eliminate the output filters typically required by Class D amplifiers. The device provides Class AB performance with Class D efficiency.
Melexis announced the MLX90283 is single phase brushless vibration motor driver IC which allows increased battery life and delivers strong and clearly detected vibrations. The device integrates hall-effect sensor, digital and power driver circuitry into a low profile Ultra-thin QFN package and introduces the new proprietary ‘Active Start’ design to improve single phase vibration motor start-up reliability. The 1.8V to 3.6V operating voltage range perfectly suits battery-powered applications.
The MD2S from US Digital is a universal programmable microstepping stepper motor driver capable of driving size 17 to 42 stepper motors. DIP switches allow for the selection of 29 microstep resolutions from 5 to 256 microsteps per step. Motor currents are selectable from 0.5A to 7.0A per winding in 0.5 Amp increments. An L-option, low current version, is available with selectable current output from 0.20 to 3.6 Amps per winding in 0.05 Amp increments.
Honeywell introduced its HIH-4030 and HIH-4031 Series Humidity Sensors with surface mount capability. An addition to the HIH series of humidity sensors, the 4030/31 series is available in tape and reel packaging for use in high-volume, automated pick-and-place manufacturing at a competitive price. It features near-linear output to provide instrumentation-quality sensor performance in a low-profile package with a low current draw. Both the
RECOM Power Laboratory announced the RP15-SAW 15W DC/DC module. The device measures 1" × 1", 50 percent the industry standard size. The device features efficiency grades up to 87 percent and trouble free operation at ambient temperatures exceeding 60°C, without external cooling measures (packing density reaches 2.3W/cm3). The outputs are trimmable in the range ±10 percent of nominal output voltage
CAP-XX expanded its product line with the High Temperature HS and HW series supercapacitors which feature a higher-boiling-point electrolyte that extends operating and storage temperature from 75°C to 85°C, and operating voltage (V) from 4.5V to 5.5V. These supercapacitors work reliably in devices where nearby components can get very hot, such as RF Power Amplifiers, which can reach 120°C during transmission, as well as in devices which are exposed to environmental high temperatures, such as a mobile phone left on the dashboard of a car in direct sunlight, or in the engine compartment in an automotive application.
W. L. Gore & Associates, Inc., announced an addition to its line of telecommunications products for improving system reliability. The Gore Cooling Filters use ambient air to cool electronic components in outdoor enclosures and Gore’s membrane technology to protect sensitive electronics from extreme environments where they may encounter corrosive particles, sand, or salty environments. Direct Air Cooling (DAC) systems with Gore Cooling Filters have fewer mechanical parts
