Texas Instruments BUF802 High-Speed Operational Amplifier
Texas Instruments BUF802 High-Speed Operational Amplifier is an open-loop, unity gain buffer with a JFET-input stage that offers low-noise, high-impedance buffering for data acquisition system (DAQ) front-ends. The BUF802 supports DC to 3.1GHz of bandwidth while providing excellent distortion and noise performance across the frequency range.
The BUF802 may be used in a composite loop with a precision amplifier in applications requiring higher precision performance. The BUF802 uses an innovative architecture to simplify the design of high-precision, wide-bandwidth composite loops.
The Texas Instruments BUF802 features an adjustable quiescent current pin, enabling designers to trade bandwidth and distortion for a lower quiescent current, thus making the part suitable across a wide frequency range. The BUF802 has integrated input and output clamps to protect the device and its subsequent signal chain from overdrive voltages.
