GENERAL DESCRIPTION
The ADA4851-1 (single), ADA4851-2 (dual), and 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 ADA4851-1W, ADA4851-2W, and ADA4851-4W are
automotive grade versions, qualified for automotive applications.
See the Automotive Products section for more details. The
ADA4851 family is designed to work over the extended
temperature range (−40°C to +125°C).
