11 December, 2001Turck has announced MK13-222Ex0-R two channel switching amplifiers - compact devices that incorporate 1 NAMUR DIN 19234 sensor, or one dry contact, per input channel and provide one single pole single throw relay per output channel.
Class D Amp Chip
15 May, 2001Zetex has announced the first product in its new class D audio amplifier family.
Triple Band Power Amp
13 March, 2001Infineon Technologies has introduced a power amplifier module for mobile phones used in 900, 1800 and 1900 MHz networks.
Audio Amplifier
12 February, 2001TelCom Semiconductor has announced its first high-performance audio amplifier.
Sound Power System
01 December, 2000Acoustic engineers now can take advantage of a computer-based system from National Instruments for measuring noise emissions.
PCI Plug-in Card
16 November, 2000A PCI plug-in card has been released that contains two AS-interface (AS-i) masters and makes it possible to operate two independent AS-i networks from a single industrial PC. Consequently, controlling two AS-i networks requires only one of the limited number of slots in the PC.
