In addition to being low cost, these amplifiers deliver solid video performance into a 150 Ω load while consuming only 3.5 mA per amplifier of supply current. Furthermore, the AD8073 is three amplifiers in a single 14-lead narrow-body SOIC package. This makes it ideal for applications where small size is essential. Each amplifier’s inputs and output are acces- sible providing added gain setting flexibility. These devices provide 30 mA of output current per amplifier, and are optimized for driving one back terminated video load (150 Ω) each. These current feedback amplifiers feature gain flatness of 0.1 dB to 10 MHz while offering differential gain and phase error of 0.05% and 0.1 °. This makes the AD8072 and AD8073 ideal for business and consumer video electronics. Both will operate from a single +5 V to +12 V power supply. The outputs of each amplifier swing to within 1.3 volts of either supply rail to accommodate video signals on a single +5 V supply. The high bandwidth of 100 MHz, 500 V/ µs of slew rate, along with settling to 0.1% in 25 ns, make the AD8072 and AD8073 useful in many general purpose, high speed applications where a single +5 V or dual power supplies up to ±6 V are needed. The AD8072 is available in 8-lead plastic DIP, SOIC, and µSOIC packages while the AD8073 is available in 14-lead plastic DIP and SOIC packages. Both operate over the commercial temperature range of 0 °C to +70°C. Additionally, the AD8072ARM oper- ates over the industrial temperature range of –40 °C to +85°C.
