ON Semi enters high-speed operational amplifier market

Posted: 24 Aug 2005 ?? ?Print Version ?Bookmark and Share


ON Semiconductor announced its entry into the high-speed operational amplifier market with the introduction of four new devices designed for the growing low-power video applications space. According to the press release, its NCS25xx family of high-speed op amps enable designers to achieve an unprecedented level of power and speed without having to make a cost tradeoff. These 200MHz devices allow video designers to achieve 0.02 percent differential gain, 0.1 differential phase, while consuming 1.1mA of current draw.

The NCS2500 is a 1.1mA, 200MHz current feedback monolithic op amp, featuring a high slew rate of 450V/?S (typ) and low differential gain and phase error. This combination of features allows designers to cleanly drive NTSC/PAL video over 75-ohm lines. The device's current feedback architecture allows for a superior large signal bandwidth at high gain values. The NCS2500 is offered in SC70-5, SOT23-5 and SOIC-8 packages.

The NCS2501 delivers the same function as the NCS2500 but includes an ENABLE input, expressly to minimize battery drain in handheld portable devices. This product is offered in the SC70-6, SOT23-6 and SOIC-8 packages.

The NCS2502 is a 110MHz, 650?A version of the NCS2501. This op amp is suitable for applications where power is the primary concern, and the full 200MHz bandwidth is not required. It is available in SC70-6, SOT23-6, and SOIC-8 packages.

The NCS2530 is a triple version (three independent op amps) of the NCS2501. Each op amp can be disabled independently of the others to provide true design flexibility. The device is offered in a TSSOP-16 package.

Bill Schromm, VP and GM of the High Performance Analog product group at ON Semi, said, "Over the next three months, we plan to introduce additional high-speed op amps with capabilities up to 1GHz, followed by the launch of a series of voltage feedback op amps suited for video matrix switching and other applications where faster slew rates are required."

The NCS25xx devices are priced from $1.05 to $1.53 per unit in 10,000 unit quantities.
