The 0.1 d B flatness specification at a 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 Ω (one 75 Ω back terminated cable). The AD810 is ideal for power sensitive applications such as video cameras, offering a low power supply current of 8.0 m A CONNECTION DIAGRAM OFFSET NULL 1 - IN 2 +IN 3 - VS 4 8 DISABLE 7 +VS 6 OUTPUT 5 OFSET NULL Figure 1. 1737-001 maximum. The disable feature reduces the power supply current to only 2.1 m A, 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 (G = +1) - 3...
