The ADA4851-1 (single), ADA4851-2 (dual), and ADA4851-4 See the Automotive Products section for more details. 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 (−40°C to +125°C). excellent overall performance and versatility. The 130 MHz,

−3 dB bandwidth and high slew rate make these amplifiers well
G = +1 3 VS = 5V
suited for many general-purpose, high speed applications.

The ADA4851 family is designed to operate at supply voltages
(dB) 1
as low as +3 V and up to ±5 V. These parts provide true single-
N 0
supply capability, allowing input signals to extend 200 mV

below the negative rail and to within 2.2 V of the positive rail.
-LOOP D –2
On the output, the amplifiers can swing within 60 mV of either
