Recently I needed to actually “see” a current waveform in the 100 uA to 5 mA range with at least a couple MHz bandwidth. This extremely expensive probe would have been perfect, but instead I built something similar for about $30 using the amazing Analog Devices AD8428 amplifier. Click “Read more” for details and a […]

Potentially, headphone listening can be technically superior since room reflections are eliminated and the intimate contact between transducer and ear mean that only tiny amounts of power are required. The small power requirement means that transducers can be operated at a small fraction of their full excursion capabilities thus reducing THD and other non-linear distortions.

Introduction An audio amplifier increases the amplitude of a small signal to a useful level, all the while maintaining the smaller signal’s detail. This is known as linearity. The greater the amplifier linearity, the more the output signal is a true representation of the input. With the ever-changing performance requirements for amplifiers in the audio

NORWOOD, Mass. (PRWEB) June 11, 2008 The ADA4939 can be used in either differential-to-differential or single-ended-to-differential configurations. An internal common-mode feedback loop allows the user to independently adjust the ADA4939 output common-mode level to match the input common mode voltage of the ADC, and at the same time achieve exceptional output balance and suppression of
NORWOOD, Mass. (PRWEB) June 16, 2008 Crest-Factor RF Detector Extends Cell Phone Battery Life by 20 Percent The ADL5502 is the industry’s first dual-function RF detector in a single package that combines an RMS detector with an envelope detector to facilitate the crest-factor measurement of complex signals. Accurate power measurement and crest-factor calculation allows
NORWOOD, Mass. (PRWEB) June 16, 2008 With the ADL5380 demodulator, base station receivers can be designed for a variety of cellular and broadband wireless data systems and standards including CDMA, W-CDMA, TD-SCDMA, PHS, LTE, and WiMAX. The ADL5380 is also an ideal solution for defense and avionics equipment, including software-defined radio, due to the broad
NORWOOD, Mass. (PRWEB) September 30, 2008 The AD4927 can be used in single-ended-to-differential and differential-to-differential configurations and is optimized for driving today’s high-performance 14- and 16-bit converters, including ADI’s AD9460 and AD9461 two-channel, 16-bit ADCs and AD9246 low-power, 14-bit ADC. The ADA4927 is especially well suited to wireless communications applications as well as medical equipment
NORWOOD, Mass. (PRWEB) December 10, 2008 The AD8295 in amp delivers the highest common-mode rejection (CMR) over frequency in its class. The CMR of competing devices typically falls off at 200 Hz, while the AD8295 maintains a minimum CMR of 80 dB to 8 kHz for all grades at G = 1. High CMR over
