GENERAL DESCRIPTION
The ADA4851-1 (single)/ADA4851-2 (dual)/ADA4851-4 (quad) are low cost, high speed, voltage feedback rail-to-rail output op amps. Despite their low price, these parts provide excellent overall performance and versatility. The 130 MHz, −3 dB bandwidth and high slew rate make these amplifiers wellsuited for many general-purpose, high speed applications.
The ADA4851 family is designed to operate at supply voltages as low as +3 V and up to ±5 V. These parts provide true singlesupply capability, allowing input signals to extend 200 mV below the negative rail and to within 2.2 V of the positive rail. On the output, the amplifiers can swing within 60 mV of either supply rail. With their combination of low price, excellent differential gain (0.08%), differential phase (0.09º), and 0.1 dB flatness out to 11 MHz, these amplifiers are ideal for consumer video applications.
