OPA361 SBOS334A − SEPTEMBER 2005 − REVISED JANUARY 2006 3V VIDEO AMPLIFIER with Internal Gain and Filter in SC70 FEATURES DESCRIPTION (cid:1) EXCELLENT VIDEO PERFORMANCE The OPA361 high-speed amplifier is optimized for 3V (cid:1) INTERNAL GAIN: 5.2V/V portable video applications. It is specifically designed to be (cid:1) compatible with the video encoders embedded in Texas SUPPORTS TV-DETECTION (cid:1) Instruments’ OMAP2420 and DaVinci processors or other COMPATIBLE WITH OMAP242x and application processors with 0.5V video output. The input DAVINCI(cid:1) PROCESSORS PP common-mode range includes GND, which allows a (cid:1) 2-POLE RECONSTRUCTION FILTER video-DAC (digital-to-analog converter) to be DC-coupled (cid:1) to the OPA361. The TV-detection feature simplifies the INPUT RANGE INCLUDES GROUND end-user interface significantly by facilitating the − DC-Coupled Input (cid:1) automatic start/stop of video transmission. INTEGRATED LEVEL SHIFTER − DC-Coupled Output(1) The output swings within 5mV of GND and 250mV to V+ − No Output Capacitors Needed with a standard back-terminated video load (150Ω). An (cid:1) internal level shift circuit prevents the output from RAIL-TO-RAIL OUTPUT saturating with 0V input, thus preventing sync-pulse (cid:1) LOW QUIESCENT CURRENT: 5.3mA clipping in common video circuits. Therefore, the OPA361 (cid:1) SHUTDOWN CURRENT: 1.5(cid:1)A is ideally suited for DC-coupling to the video load. (cid:1) SINGLE-SUPPLY: 2.5V to 3.3V The OPA361 has been optimized for space-sensitive (cid:1) SC70-6 PACKAGE: 2.0mm x 2.1mm applications by integrating internal gain setting resistors (cid:1) (G = 5.2V/V) and a 2-pole video-DAC reconstruction filter. RoHS COMPLIANT (1)Internal circuitry avoids output saturation, even with 0V sync tip In shutdown mode, the quiescent current is reduced to level at the input video signal. < 1.5µA, dramatically reducing power consumption and prolonging battery life.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure.

The typical leakage when the output is pulled high and OPA361 is disabled is only about 300pA. (cid:1) Automatic video stop if the TV (or other equipment) is disconnected. Proper implementation allows to significantly simplify the user interface. For more information, see Application Report SBOA109, OPA361 and TV Detection, available for download at www.ti.com. 11

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
