The 300 MHz, G = +2, 3 dB bandwidth, and 750 V/s slew rate make this amplifier well suited for many high speed 6.1 applications. The ADA4862-3 can also be configured to operate in gains of G = +1 and G = 1. 6.0 V = +5V S 5.9 With its combination of low price, excellent differential gain G = +2 5.8 (0.02%), differential phase (0.03), and 0.1 dB flatness out to V = 5V S R = 150 L C = 4pF L 65 MHz, this amplifier is ideal for both consumer and 5.7 V = 2V p-p OUT professional video applications. 5.6 5.5 The ADA4862-3 is designed to operate on supply voltages as 5.4 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 5.3 is equipped with a power-down feature that lowers the supply 5.2 current to 200 A/amp. The ADA4862-3 also consumes less 5.1 board area because feedback and gain set resistors are on-chip. 0.1 1 10 100 1000 FREQUENCY (MHz) Having the resistors on chip simplifies layout and minimizes the Figure 2.
