Description for the BUF802
The BUF802 device 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 3.1 GHz of bandwidth while offering excellent distortion and noise performance across the frequency range.
The BUF802 may be used in a composite loop with a precision amplifier in applications where higher precision performance is required. The BUF802 uses an innovative architecture to simplify the design of high-precision, wide-bandwidth composite loops.
The BUF802 features an adjustable quiescent current pin, which enables 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.
