Analog Devices' Low-Power, High-Speed Amplifiers for Portable Video Applications Deliver Industry's Lowest Standby Power.

NORWOOD, Mass. -- Analog Devices' new video amplifiers save battery power, board space and cost.

Extending its leadership in amplifier technology, Analog Devices, Inc. (NYSE: ADI) today introduced a pair of high-performance video amplifiers that offer low operating power and the industry's lowest standby power--enabling longer battery life in portable multimedia consumer applications, such as audio visual players and digital video cameras. The new family of low-power amplifiers, including the single ADA4850-1 and dual ADA4850-2, are designed for battery-powered video devices to efficiently playback high-quality video on televisions. When video display is not needed, the amplifiers have a patent-pending low-power standby mechanism that significantly reduces power consumption - consuming as little as one-tenth the power of the closest comparable devices. Priced to save as much as 50 percent compared to bipolar and CMOS amplifiers that have higher standby power, these amplifiers save space and component costs by integrating the low-power standby feature in a tiny 3 mm x 3 mm chip scale package.

"Our new video amplifiers allow designers to easily meet the lowest possible power levels demanded by battery-operated applications without the usual tradeoffs in image quality, or the space and price premiums associated with traditional discrete solutions," said Bob Esdale, product line director for the High-Speed Linear group at Analog Devices, Inc. "As consumer demand for handheld video applications continues to grow, Analog Devices is providing the advanced technology solutions that enable the design of applications with the optimal balance of power, size and performance at the lowest possible cost."

More about the ADA4850 - Low-Power Video Amplifiers

The ADA4850 low-power video amplifiers minimize operating current to 2.7 mA maximum and have the industry's lowest standby current at less than 1 (micro)A. This energy consumption breakthrough is achieved using a patent-pending internal shut down mechanism. The devices also include rail-to-rail outputs that allow driving line-terminated video lines on single-supply voltages as low as 2.7 V. The amplifiers have excellent differential gain and phase of 0.04 percent and 0.06 degrees, respectively. Combined with ADI's ADV7179 chip-scale video encoder, the ADA4850 enables one of the most power efficient portable television-output solutions available today.

Availability and Pricing

The ADA4850 video amplifiers are available in full production quantities. Both single and dual output devices are offered in a tiny 3 mm x 3 mm LFCSP (lead-frame chip scale package). The single ADA4850-1 is priced at $0.55 per unit, and the dual ADA4850-2 is priced at $.69 per unit in 1,000-piece quantities. For more information, please visit www.analog.com/ADA4850.
