The AD810 is a composite and HDTV-compatible, current maximum. The disable feature reduces the power supply feedback, video operational amplifier, ideal for use in systems current to only 2.1 mA, while the amplifier is not in use, to such as multimedia, digital tape recorders, and video cameras. conserve power. Furthermore, the AD810 is specified over a The 0.1 dB flatness specification at a bandwidth of 30 MHz power supply range of ±5 V to ±15 V. (G = +2) and the differential gain and phase of 0.02% and 0.04° The AD810 works well as an ADC or DAC buffer in video (NTSC) make the AD810 ideal for any broadcast quality video systems due to its unity gain (G = +1) −3 dB bandwidth of system. All these specifications are under load conditions of 80 MHz. Because the AD810 is a transimpedance amplifier, this 150 Ω (one 75 Ω back terminated cable). bandwidth can be maintained over a wide range of gains while The AD810 is ideal for power sensitive applications such as featuring a low noise of 2.9 nV/√Hz for wide dynamic range video cameras, offering a low power supply current of 8.0 mA applications.
