OPA355

OPA360 SB0S294C − DECEMBER 2003 − REVISED JULY 2004 3V Video Amplifier with 6dB Gain and Filter in SC70 FEATURES D D D D EXCELLENT VIDEO PERFORMANCE INTERNAL GAIN: 6dB 2−POLE RECONSTRUCTION FILTER SAG CORRECTION − Reduces Coupling Capacitor Size − DC-Coupled Input DESCRIPTION The OPA360 high-speed amplifier is optimized for 3V portable video applications. It has been specifically designed to be compatible with digital-to-analog converters (DACs) embedded in video processors, such as Texas Instruments’ family of Digital Media Processors and others. The input common-mode range includes GND, which allows the Video-DAC to be DC-coupled to the OPA360. The output swings within 25mV of GND and 300mV to V+ with a standard back-terminated video load (150Ω). An internal level shift circuit prevents the output from saturating with 0V input, thus preventing sync-pulse clipping in common video circuits. Therefore, the OPA360 is ideally suited for DC-coupling to the video load. If AC-coupling is preferred, the OPA360 offers a sag-correction feature that significantly reduces the size of the output coupling capacitor. The OPA360 has been optimized for space-sensitive applications by integrating sag-correction, internal gain setting resistors (G = 2), and a 2-pole video-DAC reconstruction filter. In shutdown mode, the quiescent current is reduced to < 5µA, dramatically reducing power consumption and prolonging battery life. The OPA360 is available in the tiny 2mm x 2.1mm SC70-6 package. D...
