Low Cost, High Speed, Rail-to-Rail, Output Op Amp (Quad)

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 family is designed to work over the extended temperature range (−40°C to +125°C). The ADA4851-4W and ADA4851-2W are automotive grade versions, qualified for −40°C to +125°C operation per AEC-Q100. See the Automotive Products section for more details.
