AD810AN

低功耗视频运算放大器具有禁用 Low Power Video Op Amp with Disable

Product Details

The AD810 is a composite and HDTV compatible, current feedback, video operational amplifier, ideal for use in systems such as multimedia, digital tape recorders and video cameras. The 0.1 dB flatness specification at bandwidth of 30 MHz G=+2 and the differential gain and phase of 0.02% and 0.04° NTSC make the AD810 ideal for any broadcast quality video system. All these specifications are under load conditions of 150 ohm one 75 ohm back terminated cable.

The AD810 is ideal for power sensitive applications such as video cameras, offering a low power supply current of 8.0 mA max. The disable feature reduces the power supply current to only 2.1 mA, while the amplifier is not in use, to conserve power. Furthermore the AD810 is specified over a power supply range of ±5 V to ±15 V.

The AD810 works well as an ADC or DAC buffer in video systems due to its unity gain bandwidth of 80 MHz. Because the AD810 is a transimedance amplifier, this bancwidth can be maintained over a wide range of gains while featuring a low noise of 2.9 nV/rootHz for wide dynamic range applications.
