The AD818 is a low cost video op amp optimized for use in video applications that require gains equal to or greater than +2 or -1.
The AD818 is a low‑cost video operational amplifier optimized for applications that require gains of +2 or –1, such as video cameras, monitors, CATV, and image scanners. It offers low differential gain and phase errors, single‑supply operation, low power consumption, and high output drive capability, making it suitable for driving back‑terminated cables.
The device is available in 8‑lead PDIP and SOIC packages and supports a flexible supply range, operating from a single +5 V supply or dual supplies from +5 V to +15 V. Its key performance figures include a 55 MHz 0.1 dB bandwidth, 500 V/µs slew rate, and 50 mA minimum output current.
| 3 dB Bandwidth (Gain = +2) | 55 MHz |
|---|---|
| Slew Rate | 500 V/µs |
| Settling Time to 0.01 % (±5 V step) | 80 ns |
| Minimum Output Current | 50 mA |
| Quiescent Supply Current (single +5 V) | 7.5 mA |
| Supply Voltage Range | Single +5 V or Dual +5 V to +15 V |
| Differential Gain Error | 0.01 % |
| Input Offset Voltage | 2 mV |
The AD818 has a typical slew rate of 500 V/µs.
It can operate from a single +5 V supply or from dual supplies ranging from +5 V to +15 V.
The device can source a minimum of 50 mA output current.
The AD818 draws about 7.5 mA of quiescent current when powered from a single +5 V supply.
