The (quad) are low cost, high speed, voltage feedback rail-to-rail ADA4851 family is designed to work over the extended output op amps. Despite their low price, these parts provide temperature range (40C to +125C). excellent overall performance and versatility. The 130 MHz, 4 G = +1 3 dB bandwidth and high slew rate make these amplifiers well V = 5V 3 S R = 1k L suited for many general-purpose, high speed applications. C = 5pF 2 L The ADA4851 family is designed to operate at supply voltages 1 as low as +3 V and up to 5 V. These parts provide true single- 0 supply capability, allowing input signals to extend 200 mV 1 below the negative rail and to within 2.2 V of the positive rail. 2 On the output, the amplifiers can swing within 60 mV of either 3 supply rail. 4 With their combination of low price, excellent differential gain 5 (0.08%), differential phase (0.09), and 0.1 dB flatness out to 6 11 MHz, these amplifiers are ideal for consumer video applications. 1 10 100 1k FREQUENCY (MHz) The ADA4851-1W, ADA4851-2W, and ADA4851-4W are Figure 4. Small-Signal Frequency Response automotive grade versions, qualified for automotive applications. Rev. J Information furnished by Analog Devices is believed to be accurate and reliable.
