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.
