Intersil introduces 1.4 GHz current feedback amplifiers for high speed video and communications - Intersil Elantec EL5166 and EL5167

EDP Weekly's IT Monitor, July 14, 2003

Intersil Corporation (Nasdaq:ISIL) has introduced three 1.4 GHz current feedback amplifiers (CFAs) with capacitive drive capability. The latest addition to Intersil's new high speed operational amplifier portfolio, the Elantec EL5166 and EL5167 are designed to meet the high bandwidth, high slew rate requirements of today's high performance video, test and instrumentation, and other high frequency applications.

Intersil's Elantec EL5166 and EL5167 feature unity gain bandwidths of 1.4 GHz. The EL5166 and EL5167 offer 6,000 volt-per-microsecond slew rates while exhibiting low distortion of 1.7 nanovolts (nV) per root hertz. With a supply current of just 8.3 milliamps (mA) and operating from a /- 5V split supply, Intersil's new current feedback amplifiers offer very high performance while consuming very little power.

"We continue to add best-in-class products to our Elantec family of op amps, and the EL5166 and EL5167 offer unmatched CFA performance," said Sameer Vuyyuru, Intersil's director of marketing for video and op amps. "This initial offering of current feedback amps is ideally suited for a variety of high performance video, cable driver and high frequency applications where high slew rates and wide -3dB bandwidths are critical factors. When combined with their low power consumption, these high performance CFAs are particularly well suited for portable, handheld and battery-powered applications. Intersil will continue to add single, dual and triple CFAs to this new family of op amps in the coming months."

Intersil's EL5166 and EL5167 feature excellent gain flatness, with typical performance of 1.4 GHz at -3dB and 100 MHz at 0.1dB. They feature differential gain and differential phase of 0.01% and 0.03 degrees, respectively. Both devices operate with supply voltages ranging from a single 5-volt to 10-volt supply or off a split /-5V supply, and have a wide common mode output range. The EL5166 incorporates an enable and disable function to reduce the supply current to 100 microamps per amplifier. As with all current feedback amplifiers, CFA stability is dependent upon the feedback resistor used.
