The OPA814 is a unity-gain
stable, voltage-feedback operational amplifier for
high-speed, high-precision, and wide-dynamic-range
applications.
The OPA814 has a low-noise
junction gate field-effect transistor (JFET) input stage
that features a wide gain bandwidth of 250 MHz and a supply
range from 6 V to 12.6 V. The fast slew rate of 750 V/µs
allows a wide large-signal bandwidth and low distortion when
used as high impedance buffer in high-speed digitizers,
active probes, and other test and measurement applications.
The OPA814 offers extremely low
input offset voltage of ±250 µV and offset voltage drift of
±3.5-µV/°C. The combination of picoamperes of input bias
current and low input voltage noise (5.3
nV/√ Hz) makes the OPA814 an excellent
wideband transimpedance amplifier in optical test and
communication equipment, as well as medical and scientific
instrumentation.
The OPA814 is available in an
8-pin SOIC package. This device is specified to operate over
the industrial temperature range of –40°C to +85°C.
