3 Description

The OPA891 and OPA2891 (OPAx891) are ultra-low

voltage noise, high-speed voltage feedback amplifiers

that are an excellent choice for applications requiring

low voltage noise, including communications and

imaging. The single-amplifier OPA891 and the dualamplifier

OPA2891 offer very good ac performance

with 140-MHz bandwidth (G = 2), 105-V/μs slew

rate, and 70-ns settling time (0.1). The OPAx891

are unity-gain stable with 180-MHz bandwidth. These

amplifiers have a high drive capability of 200 mA and

draw only 7.5-mA supply current per channel. With

–100 dBc of total harmonic distortion (THD) at f =

1 MHz and a very low noise of 0.95 nV/√ Hz, the

OPAx891 are designed for applications requiring low

distortion and low noise such as buffering analog-todigital

converters.
