The 300 MHz, G = +2, −3 dB bandwidth, and 750 V/μs slew rate make this amplifier well suited for many high speed applications. The ADA4862-3 can also be configured to operate in gains of G = +1 and G = −1. With its combination of low price, excellent differential gain (0.02%), differential phase (0.03°), and 0.1 dB flatness out to 65 MHz, this amplifier is ideal for both consumer and professional video applications. The ADA4862-3 is designed to operate on supply voltages as low as +5 V and up to ±5 V using only 5.3 mA/amp of supply current. To further reduce power consumption, each amplifier is equipped with a power-down feature that lowers the supply current to 200 μA/amp. The ADA4862-3 also consumes less board area because feedback and gain set resistors are on-chip. Having the resistors on chip simplifies layout and minimizes the required board space. The ADA4862-3 is available in a 14-lead SOIC package and is designed to work in the extended temperature range of −40°C to +105°C. 6.1 5.1 0.1 1000 FREQUENCY (MHz) 1 10 100 6.0 5.9 5.8 5.7 5.6 5.5 5.4 5.3 5.2 G = +2 RL = 150Ω CL = 4pF VOUT = 2V p-p VS = +5V VS = ±5V Figure 2.
