3 Description
The OPA892 and OPA2892 (OPAx892) are ultra-low
voltage noise, high-speed voltage-feedback amplifiers
that are an excellent choice for applications requiring
low voltage noise, including communication and
imaging. The single-amplifier OPA892 and the dualamplifier
OPA2892 offer very good ac performance
with a 290MHz bandwidth, a 700V/μs slew rate, and
a 30ns settling time (0.1%) for a gain of 10V/V. The
OPAx892 are stable at gains of 10 or greater and –9
or less. These amplifiers have a high drive capability
of 200mA and draw only 7.5mA of supply current
per amplifier. With a total harmonic distortion (THD)
of –68dBc at f = 1MHz, the OPAx892 are designed
for applications requiring low distortion. Because the
distortion remains low over a wide range of output
voltages, the OPAx892 is useful in large dynamicrange
applications such as imaging, sonar, and audio.
