exceptional full-power bandwidth. Using a dual ± 5V

supply, the OPA2889 can deliver a ± 4V output swing

• OUTPUT VOLTAGE SWING: ± 4V

with over 40mA drive current and 60MHz bandwidth.

• HIGH SLEW RATE: 250V/ µ s

This combination of features makes the OPA2889 an

SBOS373B – JUNE 2007 – REVISED AUGUST 2008 with a 750Ω resistor across the two op amp inputs, the voltage follower response is similar to the gain of +2V/V response of Figure 51. Reducing the value of the resistor across the op amp inputs further limits the frequency response due to increased noise gain. +5V + 0.

As a minimum, the OPA2889 requires an RB value of 50Ω to damp out parasitic-induced peaking—a direct short to ground on the noninverting input runs the risk of a very high-frequency instability in the input stage.

SBOS373B – JUNE 2007 – REVISED AUGUST 2008 NOISE PERFORMANCE High slew rate, unity-gain stable, voltage-feedback op amps usually achieve the slew rate at the expense of a higher input noise voltage. However, the 8.4nV/√Hz input voltage noise for the OPA2889 is much lower than that of comparable amplifiers.

The additional lead length and pin-to-pin capacitance introduced by the socket can create an extremely troublesome parasitic network that can make it almost impossible to achieve a smooth, stable frequency response.
