High Speed, Low Cost, Triple Op-Amp

The ADA4861-3 is a low cost, high speed, current feedback, triple op amp that provides excellent overall performance. The 730 MHz, -3 dB bandwidth, and 625 V/µs slew rate make this amplifier well suited for many high speed applications. With its combination of low price, excellent differential gain (0.01%), differential phase (0.02°), and 0.1 dB flatness out to 100 MHz, this amplifier is ideal for both consumer and professional video applications.

The ADA4861-3 is designed to operate on supply voltages as low as +5 V and up to ±5 V using only 6 mA/amplifier of supply current. To further reduce power consumption, each amplifier is equipped with a power-down feature that lowers the supply current to 0.3 mA/amp when not being used.

The ADA4861-3 is available in a 14-lead SOIC package and is designed to work over the extended temperature range of -40°C to +105°C.
