The 800 MHz, −3 dB bandwidth, and 790 V/μs slew rate make this amplifier well suited for many high speed applications. With its combination of low price, excellent differential gain (0.02%), differential phase (0.02°), and 0.1 dB flatness out to 125 MHz, this amplifier is ideal for both consumer and professional video applications. The ADA4860-1 is designed to operate on supply voltages as low as +5 V and up to ±5 V using only 6 mA of supply current. To further reduce power consumption, the amplifier is equipped with a power-down feature that lowers the supply current to 0.25 mA. The ADA4860-1 is available in a 6-lead SOT-23 package and is designed to work over the extended temperature range of −40°C to +105°C. 6.3 G = +2 6.2 VOUT = 2V p-p RF = RG = 499Ω 6.1 CLOSED-LOOP GAIN (dB) 6.0 5.9 5.8 5.7 5.6 5.5 5.4 5.3 0.1 1 10 FREQUENCY (MHz) 100 05709-003 VS = +5V VS = ±5V 1000 Figure 2. 0.1 dB Flatness Rev. 0 Information furnished by Analog Devices is believed to be accurate and reliable.
