Despite their low price, the ADA4853-1/ADA4853-2/ADA4853-3 provide excellent overall performance and versatility. The 100 MHz, −3 dB bandwidth and 120 V/μs slew rate make these amplifiers well-suited for many general-purpose, high speed applications. The ADA4853-1/ADA4853-2/ADA4853-3 voltage feedback op amps are designed to operate at supply voltages as low as 2.65 V and up to 5 V using only 1.4 mA of supply current per amplifier. To further reduce power consumption, the amplifiers are equipped with a power-down mode that lowers the supply current to less than 1.5 μA maximum, making them ideal in battery-powered applications. The ADA4853-1/ADA4853-2/ADA4853-3 provide users with a true single-supply capability, allowing input signals to extend 200 mV below the negative rail and to within 1.2 V of the positive rail. On the output, the amplifiers can swing within 200 mV of either supply rail. With their combination of low price, excellent differential gain (0.2%), differential phase (0.10°), and 0.5 dB flatness out to 22 MHz, these amplifiers are ideal for video applications. The ADA4853-1 is available in a 6-lead SC70, the ADA4853-2 is available in a 16-lead LFCSP_VQ, and the ADA4853-3 is available in both a 16-lead LFCSP_VQ and a 14-lead TSSOP. The ADA4853-1 temperature range is −40°C to +85°C, while the ADA4853-2/ADA4853-3 temperature range is −40°C to +105°C. 6.5 6.4 6.3 6.2 6.1 6.0 5.9 5.8 5.7 5.6 5.5 0.1 1 10 40 FREQUENCY (MHz) VS =5V RL =150Ω G= +2 0.1V p-p 2.0V p-p Figure 5. 0.5 dB Flatness Frequency Response |
