Despite their low price, the ADA4850-1/ ADA4850-2 provide excellent overall performance and versatility. The 175 MHz −3 dB bandwidth and 220 V/µs slew rate make these amplifiers well-suited for many general- purpose, high speed applications. The ADA4850-1/ADA4850-2 are designed to operate at supply voltages as low as 2.7 V and up to 6 V at 2.4 mA of supply current per amplifier. In power-down mode, the supply current is less than 150 nA, ideal for battery-powered applications. The ADA4850 family provides users with a true single-supply capability, allowing input signals to extend 200 mV below the negative rail and to within 2.2 V of the positive rail. The output of the amplifier can swing within 80 mV of either supply rail. With its combination of low price, excellent differential gain (0.12%), differential phase (0.09º), and 0.1 dB flatness out to 14 MHz, these amplifiers are ideal for video applications. The ADA4850-1/ADA4850-2 are designed to work in the extended temperature range of −40°C to +125°C. 1 100 10 1000 FREQUENCY (MHz) –6 –4 –5 –2 –3 0 –1 2 1 G = +1 VS = 5V RL = 1kΩ VOUT = 0.1V p-p Figure 3.
