3 Description
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.
