The ADA4862-3 (triple) is a low cost, high speed, internally The ADA4862-3 is available in a 14-lead SOIC package and is fixed, G = +2 op amp, which provides excellent overall designed to work in the extended temperature range of −40°C performance for high definition and RGB video applications. to +105°C. 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
