NORWOOD, Mass., 17 Sept. 2008. Analog Devices Inc. (ADI) in Norwood, Mass., is introducing an integrated precision operational amplifier (op amp) with on-chip over-voltage protection circuitry for industrial equipment designers.
The ADA4091-2 offers specified performance -- including the on-chip over-voltage circuitry -- to simplify equipment design and error analysis in industrial process controls, battery-powered instrumentation, power supply control, protection systems, and remote sensors.
precision op amp affords the industry's most reliable, accurate, easy-to-use alternative to competing discrete analog input solutions.
"Industrial amplifiers are subject to fault voltages from a variety of sources, including electro-magnetic interference, damaged cabling, lightning strikes and other disturbances on the power grid, incorrect hookups to other system components and power-line surges when power to the system is restored after routine service or equipment upgrades," says Steve Sockolov, product line director at the ADI Precision Signal Processing segment. "Such over-voltage conditions can cause phase inversion or damage the amplifier and other circuitry, resulting in system lock-up or outright failure."
The 1.5-MHz op amp features a 350-micro amps-per-channel supply current, a 0.5-volts-per-microsecond slew rate, and offset voltage of 500 microvolts maximum. For more information contact ADI online at www.analog.com.
