Analog Devices Inc. AD810 Low Power Video Op-Amps
Analog Devices Inc. AD810 Video Low Power Op-Amps are high-speed, HDTV-compatible, and current feedback video operational amplifiers that are ideal for any broadcast quality video system. These Op-Amps exhibit 0.1dB flatness specification at a bandwidth of 30MHz (G = +2) and the differential gain with phase of 0.02% and 0.04° (NTSC). The AD810 amplifiers work well as an ADC or DAC buffer in video systems due to its unity gain (G = +1) −3dB bandwidth of 80MHz. The disable feature of these video amplifiers reduces the power supply current to just 2.1mA when an amplifier is not in use to conserve power. The AD810 amplifiers are ideal for power sensitive applications such as video cameras offering a low power supply current of 8.0mA (maximum). Typical applications include multimedia systems, digital tape recorders, video cameras, ADC or DAC buffers, and DC restoration circuits.
