The 800 MHz, R = R = 499 F G 3 dB bandwidth, and 790 V/s slew rate make this amplifier 6.1 well suited for many high speed applications. With its combination 6.0 of low price, excellent differential gain (0.02%), differential 5.9 phase (0.02), and 0.1 dB flatness out to 125 MHz, this amplifier V = +5V S 5.8 is ideal for both consumer and professional video applications. V = 5V S 5.7 The ADA4860-1 is designed to operate on supply voltages as 5.6 low as +5 V and up to 5 V using only 6 mA of supply current. 5.5 To further reduce power consumption, the amplifier is 5.4 equipped with a power-down feature that lowers the supply 5.3 current to 0.25 mA. 0.1 1 10 100 1000 FREQUENCY (MHz) The ADA4860-1 is available in a 6-lead SOT-23 package and Figure 2. 0.1 dB Flatness is designed to work over the extended temperature range of 40C to +105C.
