ADA4862-3YRZ-RL7

The ADA4862-3 (triple) is a low cost, high speed, internally fixed, G = +2 op amp, which provides excellent overall performance for high definition and RGB video applications. 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.
