Texas Instruments OPA814 Unity-Gain Stable Voltage-Feedback Operational Amplifier (Op Amp) is designed for high-speed, high-precision, and wide-dynamic-range applications. The OPA814 has a low-noise junction gate field-effect transistor (JFET) input stage with a wide gain bandwidth of 250MHz and a supply range from 6V to 12.6V. The fast slew rate of 750V/µs allows a wide large-signal bandwidth and low distortion when used as a high-impedance buffer in high-speed digitizers, active probes, and other test and measurement applications.
The Texas Instruments OPA814 offers an extremely low input offset voltage of ±250µV and offset voltage drift of ±3.5µV/°C. The combination of picoamperes of input bias current and low input voltage noise (5.3nV/√ Hz) makes the OPA814 an excellent wideband transimpedance amplifier in optical test and communication equipment and 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.
