Descripción de OPA814
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.
