8/20/2004 - Texas Instruments Incorporated (TI) (NYSE: TXN) announced a high-speed video amplifier in a small SC70 package from the company´s Burr-Brown product line. Featuring 6dB gain, two-pole digital-to-analog converter (DAC) reconstruction filter and a shutdown function, the device is ideal for the composite video output in 3V portable applications such as digital cameras, camera phones, set-top boxes, and video games.

The OPA360 is compatible with DACs embedded in video processors, including TI's digital media processors. The input voltage range includes ground which allows the embedded Video-DAC to be DC-coupled into the OPA360.
"The OPA360 provides excellent video performance for either AC-coupling or DC-coupling to the video load," said Frank Haupt, strategic marketing engineer of TI's high-performance amplifier products. "For AC-coupled outputs, the SAG-correction feature significantly reduces the big and expensive coupling capacitors required by standard video circuits. For DC-coupling, the OPA360 uses an integrated level shifter to prevent the output from clipping - even when the lowest sync-pulse level on the input is 0V."
An internal DAC reconstruction filter removes out-of-band (5MHz) sampling artifacts. In shutdown mode, the quiescent current is reduced to <5uA - dramatically reducing power consumption and extending battery life.
The OPA360 is available now in the 2mm x 2.1mm SC70-6 package from TI and its authorized distributors. The device is priced at $0.49 in 1,000 piece quantities (suggested resale pricing). Related low-voltage video amplifier products, OPA355 and OPA357, are also available. OPA358, a companion product to OPA360, will be available in 4Q 2004.
