The advantage of this preamplifier design is that the dc output voltages of the individual operational
amplifiers do not go into saturation and no compensating source is needed at the input.
NYSE:TRW), a world leader in advanced semiconductors, has developed a highly efficient microwave power
amplifier chip that delivers world record levels of power per unit of semiconductor area for integrated circuits operating at more than 20 billion cycles per second (20 GHz).
The D2Audio Corporation, maker of the world's only Intelligent Digital
Amplifiers, supplies a full line of cost-efficient, powerful, multi-channel platforms.
These new Reference
amplifiers are quite a bit smaller than the models they replace, making installation a far easier process.
ADI's portfolio of free support tools for
amplifiers helps design engineers quickly and efficiently select the right products, conduct real-time simulations, and trial-test various configurations.
Headquartered in Inglewood, California, the company shipped its first batch of
amplifiers in early 2000 to customers in the wireless communication and the electromagnetic compatibility and susceptibility (EMC) industries.
The D2Audio Corporation, developer of the world's only intelligent digital audio
amplifiers, supplies a full line of cost-efficient, powerful, multi-channel platforms including ICs and firmware with market leading performance and superior sound quality for digital media applications in consumer, professional, and automotive industries.
These
amplifiers are both protocol and data-rate independent and can be used as a transmitter power-amp, a receiver pre-amp or as an in-line
amplifier.
This family offers low-power performance as stand-alone devices or as MCU-controlled
amplifiers, while still fitting the standard operational
amplifier footprint.
Findings verified that JamTech's technology exceeds measurements typically achieved by traditional analog pulse width modulation (PWM) Class D
amplifiers and delta-sigma PWM digital
amplifiers for both absolute dynamic range and spectral noise floor, two important measures of fidelity in digital audio systems.
It enables the incorporation of optical
amplifiers as a new network element with minimal changes to the network's hardware and operating software.
This is compared to a typical range of 72-78dB (12-13 bits) for traditional analog PWM Class D
amplifiers and 84-90dB (14-15 bits) for delta-sigma PWM digital
amplifiers.
