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 well
suited 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 single-
supply 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.
The ADA4851 family is designed to work over the extended
temperature range (40°C to +125°C).
