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 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 mA maximum. 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 (G = +1) −3 dB bandwidth of 80 MHz. Because the AD810 is a transimpedance amplifier, this bandwidth can be maintained over a wide range of gains while featuring a low noise of 2.9 nV/√Hz for wide dynamic range applications.
- Professional video cameras
- Multimedia systems
- NTSC-, PAL-, and SECAM-compatible systems
- Video line drivers
- ADC or DAC buffers
- DC restoration circuits
Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The Universal Single High Speed Amplifier Evaluation Boards are bare boards that enable users to quickly prototype a variety of amplifier circuits, which minimizes risk and reduces time to market. These boards are all RoHs Compliant. See ordering guide below on what board to order by lead count and package.
