3 Description
The OPA891 and OPA2891 (OPAx891) are ultralow
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 dual-amplifier OPA2891 offer very good ac
performance with 140MHz bandwidth, gain (G) =
2V/V, 105V/μs slew rate, and 70ns settling time
(0.1%). The OPAx891 are unity-gain stable with
180MHz bandwidth. These amplifiers have a high
drive capability of 200mA and draw only 7.5mA
supply current per channel. With –100dBc of total
harmonic distortion (THD) at f = 1MHz and a very
low noise of 0.95nV/√Hz, the OPAx891 are designed
for applications requiring low distortion and low noise
such as buffering analog-to-digital converters.
